Essay on Solar System

The solar system comprises all the planets that revolve around the sun. The solar system also contains moons, asteroids, comets, minor planets, and different types of gases and dust.

The planets are categorised into two categories: internal planets and outer planets. Mercury, Venus, Earth, Mars, Jupyter, Saturn, Uranus, and Neptune are called inner planets . Earlier, there were nine planets considered till 2006, but now, Pluto does not lie in the list of planets, it does not meet the standard set for the planets.

It is now termed a dwarf planet. In our solar system, the earth is the only planet where life exists. There are many solar systems that exist in the universe, it is more than 500. Our solar system includes the Kuiper belt that lies past Neptune’s orbit.

The Sun is a star that is made up of massive hot gas that gives us heat and light . The Sun is the focal point of the solar system, every substance in the solar system revolves around the Sun. There are eight planets in the solar system, Mercury is the closest planet to the Sun and the smallest planet in the solar system whereas Neptune is the farthest one and Jupiter is the biggest planet in the solar system.

Only Earth has a supportive environment for living creatures. The Earth rotates around its own axis and revolves around the Sun, similarly the moon orbits around the Earth. For complete rotation the earth takes one day and for completing one cycle around the sun it takes 365 days. It is what we call one year and due to gravity we all are stuck to the surface of the Earth.

A Comet is a large body in space made of rocks, ice, and frozen gas. The centre of a comet is called the nucleus. Asteroids are also large bodies in space made of rocks and minerals, they mostly orbit the sun between Mars and Jupiter in an area called the Asteroid Belt.

The solar system comprises eight planets, about 170 natural planetary satellites, and uncountable asteroids, meteorites, and comets. The solar system is situated within the Orion-Cygnus arm of the Milky way galaxy . Alpha Centauri made up of the stars Proxima Centauri, Alpha Centauri A, and Alpha Centauri B are the closest star systems to the solar system. The sun which is located at the centre of the solar system affects the motion of the body through its gravitational force. It contains more than 99% mass of the system.

Essay on Solar System

500+ words essay on solar system.

The Sun and all other planets and celestial bodies that revolve around it are together called a solar system. Our solar system consists of eight planets and an asteroid belt. These planets are termed inner and outer planets. Earth, Venus, Mercury and Mars are considered inner planets closer to the Sun and smaller, also known as terrestrial planets. The remaining four planets, Jupiter, Saturn, Uranus, and Neptune, are outer planets that are massive and termed giant planets.

This essay will discuss our solar system and give a detailed summary of the eight planets.

Planets are large celestial bodies that revolve around the Sun in fixed orbits. They don’t have their own lights and use the Sun’s light to reflect light. As stars, planets don’t twinkle because they are closer to us. The planets Mercury, Venus, Earth and Mars, remain in the inner solar system, and the outer solar system planets are Jupiter, Saturn, Uranus, and Neptune. Among all the planets, Earth is the only planet where life exists.

Satellites are objects that revolve around the Sun. Satellites can be categorised into two types – natural and man-made. For example, the Moon is a natural satellite that revolves around the Earth.

Man-made Satellite

Man-made satellites are artificial satellites sent to space to gather information about other planets. The first artificial satellite sent by India into space is Aryabhatta.

Asteroids are small, rocky objects that revolve around the Sun. Most asteroids are made of different rocks, but some have clays or metals, such as nickel and iron. Asteroids have irregular shapes and are not round-like planets.

Comets are irregularly shaped bodies composed of non-volatile grains and frozen gases. For example, Haley’s comet is a comet that occurs once every 76 years.

Dwarf planets

Dwarf planets are heavenly bodies that are too small to be considered a planet but too large to fall under smaller categories. Example: Pluto

Our Solar System

The nearest and the smallest planet in our solar system is Mercury. The planet is hidden under the Sunlight, which can only be seen before sunrise or sunset.

Venus is the closest and brightest planet in our solar system other than the Sun and the Moon. It is known as the morning and evening star because it appears in the eastern sky before Sunrise and in the western sky after sunset.

In our solar system, the Earth is the only planet that favours life. On this planet, life is possible because of conditions like water and atmosphere and the favourable distance from the Sun. The Earth’s rotation of axis is tilted, due to which we witness seasonal changes, and the Moon is the only natural satellite of planet Earth. From outer space, the colour of the Earth appears bluish-green as light from the landmass and water bodies gets reflected.

Mars is the fourth planet from the Sun. It is often called the “Red Planet” because the reddish iron oxide prevalent on its surface gives it a reddish appearance. Mars has two natural satellites.

Jupiter is the largest planet in our solar system. So big that it can accommodate 1300 piles of Earth. However, it is only 318 times heavier than Earth. Jupiter has at least 67 Moons. Jupiter has a big red spot, a gigantic one twice as wide as the Earth, that has been swirling for many years.

Saturn is the second-largest planet in our solar system. It is unique as it has thousands of beautiful rings. Saturn has numerous Moons.

Uranus and Neptune

Uranus rotates from west to east. Its axis has a huge tilt, making it look like it’s spinning on its side. Neptune is the eighth and farthest planet in our solar system. It has powerful winds, which are more potent than any other planet in the solar system.

Scientists and astronomers have been studying our solar system for centuries, and the findings are pretty interesting. Various planets that form a part of our solar system have their unique geological features, and all are different from each other in several ways. But, unfortunately, after years of exploration, the Universe has still more mysteries that are left unknown.

From our BYJU’S website, students can also access CBSE Essays related to different topics. It will help students to get good marks in their exams.

Frequently Asked Questions on Solar system Essay

Are there any other systems present in the universe.

Research has shown that there are several other systems existing in the universe other than our Solar system.

Does the solar system only consist of planets?

No, the solar system also consists of dwarf planets, asteroids, comets, etc.

Has the Solar system fully been discovered?

Although there are several types of research going on, there are still many undiscovered and unreachable regions of the Solar system.

Introduction to Essay Writing on Solar System on Vedantu

An essay is a piece of writing where an author expresses in detail all the information on a particular topic. An essay differs from other writing because it is more structured and it provides the author with their own perspective. In this particular essay, we shall know in detail about the solar system. Use this essay as a reference essay and try writing an essay on the solar system.

Let us begin our learning!

Essay on Solar System

The solar system consists of the sun, eight planets, and sixty-seven satellites of the planets, and a large number of small bodies (comets and asteroids). Earlier, Pluto was considered the smallest planet but now Pluto is not recognized anymore as a planet. The inner solar system comprises Sun, Mercury, Venus, Earth, and Mars. Jupiter, Saturn, Uranus, and Neptune form the outer solar system. These four planets are massive in size; hence they are called Giant Planets. Each planet revolves around the sun in its own orbits at its own speed.

Let us explore all the celestial bodies present in the Solar system.

The Sun was born 4.6 billions of years ago and it was formed from a giant rotating cloud of gasses and dust known as solar Nebula. The sun is the biggest star present at the center of the solar system. It is a self-luminous sphere of gasses. Its gravitational force holds the entire solar system. It has a radius of 695,508 kilometers and is 150 million kilometers away from Earth.

Mercury is the smallest and closest planet to the sun. It is also called Swift planet because it completes its revolution in 88 earth days. Its diameter is only one third of Earth but its density is about the same. The temperature of this planet is as high as 450 degrees Celsius in the mornings and nights are freezing cold. The surface of this planet is filled with craters, mountains and valleys.

Venus is the second closest planet to the sun and the hottest. Venus is the brightest planet and hence called the morning star. Venus is named after the Roman Goddess of love and beauty. Venus completes one revolution around the sun in 255 earth days. Venus spins clockwise on its orbits unlike other planets. Its surface is covered with clouds, craters, mountains and lava plains.

The third planet in the solar system is Earth. This is the only planet that sustains life. It is called the Blue planet because 70% of the earth's surface is covered with water. Earth takes 365 days to complete one revolution around the sun. This planet has only one natural satellite, the Moon.

The fourth planet from the sun in the solar system is Mars. It appears as a red-orange ball because of the presence of iron oxide and so it is called the Red planet. It is the second smallest planet after Mercury. Mars is named after the Roman God of war. Its surface is covered with volcanoes, craters all over.

Jupiter is the largest planet in the solar system. Jupiter is rich in hydrogen and helium gas and so it is also called a Gas Giant planet. Jupiter takes 4333 earth days to complete one revolution around the sun. This planet has 79 satellites. Jupiter has four rings.

Saturn is the least dense planet in the solar system. It is the second-largest planet. Saturn can float in water because it is made up of gasses like helium. The beautiful rings around the planet are made up of bits of ice, rock, and dust. Saturn revolves very slowly around the sun. This planet is named after the Roman God of agriculture and wealth.

Uranus is the coldest planet in the solar system. It takes 84 earth years to complete one revolution around the sun. Uranus is called an ice giant planet because its layer is made of ice and hydrogen, helium and methane. Uranus looks blue in color because of the presence of methane. Uranus has 27 satellites.

Neptune is the eighth and the farthest planet from the sun in the solar system. Neptune is named after the Roman God of the sea. Its atmosphere is made up of hydrogen, helium and methane and the presence of methane gives the color blue to the planet. It takes 165 earth years to complete one revolution. Neptune has 6 rings.

Comets and Asteroids:

Comets and Asteroids are the small celestial bodies that rotate around the sun. Asteroids are made up of rocks, metals and water. Comets are made up of frozen ammonia, methane and small amounts of rocky material.

7. What is the process of planet formation called?

The process by which planets are formed is called planetesimals. In the process, the clouds of gasses came together due to gravitational differences . The area of more clouds had higher gravitation and thus attracted more clouds towards them. The ball of clouds takes a round shape through the process of accretion.  

Read the article on Solar systems on the website of Vedantu.

8. What are terrestrial and jovian planets?

Terrestrial planets are planets closer to the Sun, it is also called inner planets. These planets are also called Earth-like planets as their features are similar to the Earth. It includes four planets which are Mercury, Venus, Earth, and Mars. Whereas jovian planets are the outer planets which are farther from the Sun. They are also called Jupiter-like planets as they share features similar to Jupiter. It includes Jupiter, Saturn, Uranus, and Neptune.

9. Can we draw diagrams in an essay? 

Some diagrammatic representation in an essay can be done. However, it is recommended that we should avoid drawing diagrams in an essay as it breaks the flow of the writing. Read some good essays to improve your writing style.

Our Solar System: Facts

There are many planetary systems in the universe, with planets orbiting host stars. Our planetary system is called “the solar system” because we use the word “solar” to describe things related to our star, after the Latin word for Sun, "solis."

Our solar system is made up of a star, eight planets, and countless smaller bodies such as dwarf planets, asteroids, and comets.

Our solar system orbits the center of the Milky Way galaxy at about 515,000 mph (828,000 kph). We’re in one of the galaxy’s four spiral arms.

Sun in Milky Way

It takes our solar system about 230 million years to complete one orbit around the galactic center.

Illustration of spacecraft heading toward center of Milky Way.

There are three general kinds of galaxies: elliptical, spiral, and irregular. The Milky Way is a spiral galaxy.

A spiral galaxy, a fuzzy oval tilted diagonally and partially towards the viewer. The center glows in warm colors, and has two prominent spiral arms around it, with bright points of star formation. The galaxy appears centrally in a field of small stars and galaxies on a dark background.

Our solar system is a region of space. It has no atmosphere. But it contains many worlds – including Earth – with many kinds of atmospheres.

A setting, waning crescent moon amid the thin line of Earth's atmosphere.

The planets of our solar system – and even many asteroids – hold hundreds of moons in their orbits.

Our solar system is the only one known to support life. So far, we only know of life on Earth, but we’re looking for more everywhere we can.

A view of Earth in the blackness of space, looking toward the Pacific Ocean, shows only blue ocean and clouds.

NASA’s Voyager 1 and Voyager 2 are the only spacecraft to leave our solar system. Three other spacecraft – Pioneer 10, Pioneer 11, and New Horizons – will eventually hit interstellar space.

Voyager 1 and the solar system with orbits

Size and Distance

Our solar system extends much farther than the eight planets that orbit the Sun. The solar system also includes the Kuiper Belt that lies past Neptune's orbit. This is a sparsely occupied ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto .

Beyond the fringes of the Kuiper Belt is the Oort Cloud . This giant spherical shell surrounds our solar system. It has never been directly observed, but its existence is predicted based on mathematical models and observations of comets that likely originate there.

The Oort Cloud is made of icy pieces of space debris - some bigger than mountains – orbiting our Sun as far as 1.6 light-years away. This shell of material is thick, extending from 5,000 astronomical units to 100,000 astronomical units. One astronomical unit (or AU) is the distance from the Sun to Earth, or about 93 million miles (150 million kilometers). The Oort Cloud is the boundary of the Sun's gravitational influence, where orbiting objects can turn around and return closer to our Sun.

The Sun's heliosphere doesn't extend quite as far. The heliosphere is the bubble created by the solar wind – a stream of electrically charged gas blowing outward from the Sun in all directions. The boundary where the solar wind is abruptly slowed by pressure from interstellar gases is called the termination shock. This edge occurs between 80-100 astronomical units.

Two NASA spacecraft launched in 1977 have crossed the termination shock: Voyager 1 in 2004 and Voyager 2 in 2007. Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. But it will be many thousands of years before the two Voyagers exit the Oort Cloud.

Of the eight planets, Mercury and Venus are the only ones with no moons. The giant planets Jupiter and Saturn lead our solar system’s moon counts. In some ways, the swarms of moons around these worlds resemble mini versions of our solar system. Pluto, smaller than our own moon, has five moons in its orbit, including Charon, a moon so large it makes Pluto wobble. Even tiny asteroids have moons. In 2017, scientists found asteroid 3122 Florence had two tiny moons .

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.

At the center, gravity pulled more and more material in. Eventually, the pressure in the core was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy. With that, our Sun was born, and it eventually amassed more than 99% of the available matter.

Matter farther out in the disk was also clumping together. These clumps smashed into one another, forming larger and larger objects. Some of them grew big enough for their gravity to shape them into spheres, becoming planets, dwarf planets, and large moons. In other cases, planets did not form: the asteroid belt is made of bits and pieces of the early solar system that could never quite come together into a planet. Other smaller leftover pieces became asteroids, comets, meteoroids, and small, irregular moons.

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets. They are all small with solid, rocky surfaces.

Meanwhile, materials we are used to seeing as ice, liquid, or gas settled in the outer regions of the young solar system. Gravity pulled these materials together, and that is where we find gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune.

Solar System 101

The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. The star system we’re most familiar with, of course, is our own.

Home sweet home

If you were to look at a giant picture of space, zoom in on the Milky Way galaxy , and then zoom in again on one of its outer spiral arms, you’d find the solar system. Astronomers believe it formed about 4.5 billion years ago, when a massive interstellar cloud of gas and dust collapsed on itself, giving rise to the star that anchors our solar system—that big ball of warmth known as the sun.

Along with the sun, our cosmic neighborhood includes the eight major planets. The closest to the sun is Mercury , followed by Venus , Earth, and Mars . These are known as terrestrial planets, because they’re solid and rocky. Beyond the orbit of Mars, you’ll find the main asteroid belt , a region of space rocks left over from the formation of the planets. Next come the much bigger gas giants Jupiter and Saturn , which is known for its large ring systems made of ice, rock, or both. Farther out are the ice giants Uranus and Neptune . Beyond that, a host of smaller icy worlds congregate in an enormous stretch of space called the Kuiper Belt. Perhaps the most famous resident there is Pluto . Once considered the ninth planet, Pluto is now officially classified as a dwarf planet , along with three other Kuiper Belt objects and Ceres in the asteroid belt.

Moons and other matter

More than 150 moons orbit worlds in our solar system. Known as natural satellites, they orbit planets, dwarf planets, asteroids, and other debris. Among the planets, moons are more common in the outer reaches of the solar system. Mercury and Venus are moon-free, Mars has two small moons, and Earth has just one. Meanwhile, Jupiter and Saturn have dozens, and Uranus and Neptune each have more than 10. Even though it’s relatively small, Pluto has five moons, one of which is so close to Pluto in size that some astronomers argue Pluto and this moon, Charon, are a binary system.

This digital collage brings together our solar system and points beyond in one view.

Too small to be called planets, asteroids are rocky chunks that also orbit our sun along with the space rocks known as meteoroids. Tens of thousands of asteroids are gathered in the belt that lies between the orbits of Mars and Jupiter. Comets, on the other hand, live inside the Kuiper Belt and even farther out in our solar system in a distant region called the Oort cloud .

Atmospheric conditions

The solar system is enveloped by a huge bubble called the heliosphere . Made of charged particles generated by the sun, the heliosphere shields planets and other objects from high-speed interstellar particles known as cosmic rays. Within the heliosphere, some of the planets are wrapped in their own bubbles—called magnetospheres —that protect them from the most harmful forms of solar radiation. Earth has a very strong magnetosphere, while Mars and Venus have none at all.

Most of the major planets also have atmospheres . Earth’s is composed mainly of nitrogen and oxygen—key for sustaining life. The atmospheres on terrestrial Venus and Mars are mostly carbon dioxide, while the thick atmospheres of Jupiter, Saturn, Uranus, and Neptune are made primarily of hydrogen and helium. Mercury doesn’t have an atmosphere at all. Instead scientists refer to its extremely thin covering of oxygen, hydrogen, sodium, helium, and potassium as an exosphere.

Moons can have atmospheres, too, but Saturn’s largest moon, Titan, is the only one known to have a thick atmosphere, which is made mostly of nitrogen.

Life beyond?

For centuries astronomers believed that Earth was the center of the universe, with the sun and all the other stars revolving around it. But in the 16th century, German mathematician and astronomer Nicolaus Copernicus upended that theory by providing strong evidence that Earth and the other planets travel around the sun.

Today, astronomers are studying other stars in our galaxy that host planets, including some star systems like our own that have multiple planetary companions. Based on the thousands of known worlds spotted so far, scientists estimate that billions of planetary systems must exist in the Milky Way galaxy alone.

So does Earth have a twin somewhere in the universe? With ever-advancing telescopes, robots, and other tools, astronomers of the future are sure to find out.

The Origins of the Solar System Essay

Introduction.

The origin of the Sun and its orbiting planets has been a point of hypothesis and conjecture ever since man looked upon the stars and planets and wondered about their origins. For the ancient Greek and Roman civilization the celestial bodies they observed in the sky were thought of as Gods and Goddesses, looking down up the Earth from some form of godlike platform. Today, it is an established fact that the heavenly bodies we see in the night sky are composed of planets and stars, celestial bodies of rock, gas and varying forms of elements that were formed billions of years ago. Even though such objects have been observed for hundreds of years it is only within the last 200 that humanity has begun to understand their unique qualities. While there have been conjectures, varying hypothesis and age old established theories what must be understood is that as the science of astronomy evolves humanity begins to slowly adapt to new information, new discoveries and subsequent re-evaluations of what we knew of as fact. For example, early studies of astronomy adopted the geocentric model in that they believed that the sun, planets, moon and stars revolved around the Earth, not only that there was also the belief that the Earth was in fact flat (Copernicus, 2009: 83). It is based on this that when examining the established theories on the origins of the solar system one must do so with both an open yet skeptical mind, taking into account the given data and observations yet not clearly adhering to any one theory as being definitive proof.

Another interesting topic that should be taken note of is the origin of the Earth itself for just as there have been numerous theories as to the origin of the solar system there have been a plethora of theories which have attempted to determine the origin of the Earth itself. Our home planet is unique in that it is the only planet within our solar system that has sufficiently developed to be able to support life. While there have been varying accounts of how life came to be on Earth, with religion and science vying for attention, the fact remains that the uniqueness of our planet should not be underestimated and as such bodes a certain degree of curiosity as to the origins of the unique circumstances that enabled Earth to become what it is today. It is based on the various questions presented that this paper will explore the origins of the solar system and of Earth itself in order to attain a clear picture of where it came from and what its possible end could be.

The Nebular Hypothesis

Currently, one of the most widely accepted theories regarding the formation of the solar system is that of the nebular hypothesis which states that the solar system originated from a molecular cloud wherein through the introduction of an external force caused a gravitational collapse of the fragment resulting in the creation of A pre-solar nebula that would eventually become our solar system (Glassmeier, 2006: 1 – 5). While there has been no definitive evidence as to the exact origin of the external force that caused a section of the molecular cloud to collapse rather than dispersing it into space it is theorized that the energy from a nearby supernova produced sufficient enough force to cause the collapse and help trigger the necessary events needed to create the solar system. While few studies dispute the nebular hypothesis several do call into question the theory that a supernova caused the initial collapse. Studies such as those by Woolfson (2010) state that the energies from a supernova instead of causing a section of the molecular cloud to collapse would have actually dispersed a majority of the cloud into space thus preventing the formation of the solar system (Woolfson, 2000: 1 – 15). Furthermore, while the nebular hypothesis has been well established as a guiding concept in understanding the creation of celestial bodies little is known as to the precise origins of the molecular cloud that gave birth to the solar system itself. Several scientists such as Lognonne et al. (2007) state that origin of the Sun and its surrounding planets was a molecular cloud and go to great lengths explaining how it led to the creation of the solar system yet a lot of studies neglect to mention how the molecular cloud came to be in the first place (Lognonne et al., 2007: 1 -3)

Origin of the Molecular Cloud

While this paper has so far expounded on the nebular theory involving the Solar system’s origins as coming from a giant molecular cloud a rather interesting question comes to mind, “if the origin of the solar system is that of a giant molecular cloud where did the molecular cloud come from?”. Studies such as those by Sorrell (2008) explain that while our own sun is 4.5 billion years old the age of the universe itself has been estimated at roughly 13.75 billion years (estimate subject to change due to varying accounts as to the proper calculation) (Sorrell, 2008: 45 – 49). Furthermore it must be noted that our sun is not the oldest sun in the universe let alone in our galaxy and in fact can be considered in the prime of its “youth” as a main sequence star (Naylor, 2009: 432). It has been theorized by researchers such as Freire (2008) that a few billion years after the Big Bang, Super Massive stars, many times the temperature of our current sun and several times its size, were among the first stars to form within the universe (Freire, 2008: 459-460). These celestial bodies were able to grow to such great size due to less “competition” for available materials in order to coalesce into stars; it must be noted though that at this point in time planets were unable to form due to the lack of heavier elements in which a sufficient enough solid mass could coalesce into a planet (Dessart, 2010: 2113-2125).

Rather interestingly, it was actually due to the inherent instability of Super Massive stars that the universe became what it is today; this is due to the theory that as a direct result of their internal instability most of the original Super Massive stars became supernovas which actually caused the original molecular clouds in the universe to form (Dessart et al., 2010: 2120 – 2125). The original state of the universe was actually more “pure” in the sense that there was a distinct lack of heavier elements, as such the question of “where did the heavier elements come from?” comes to mind. This is actually resolved by looking at the activity of our own sun wherein through a process called stellar nucleosynthesis in which the nuclear reactions within the sun itself is able to help build the nuclei of elements that are heavier than hydrogen (Chiosi, 2010).

Runaway Star Hypothesis

Runaway Star Captured by Hubble Space Telescope

In relation to the explanation of the origins of the molecular cloud as coming from the debris from Super Massive stars Courtland (2010) presents a new theory that details exactly how the molecular cloud that spawned the solar system came to be. In her study which involved the examination of various meteorites she discovered that sealed within the rock were calcium-aluminum rich incisions (Al-26) that could only have been formed by stars that were at least 10 times as massive as the sun (Courtland, 2010: 8). Due to the fact that Super Massive stars usually form within clusters with Al 26 usually decaying rapidly due to the intense heat within such clusters it is hypothesized by Courtland (2010) that a run away must have been tossed out of its orbit as a direct result of either an explosion of a nearby Super Massive star or due to combined gravitational push by its sibling stars within the cluster (Courtland, 2010: 8). Due to Super Massive stars having a relatively short life cycle when the star became a supernova the dispersed molecules and elements became the molecular cloud that we know of today as being the primary basis of the nebular hypothesis.

Formation of the Sun and Planets

Creation of the sun.

Life Cycle of the Sun

Since this paper has now established the various theories which attempt to explain the origins of the molecular cloud that brought about the creation of the solar it is now necessary to explain the current prevailing theory on how the planets and the creation of the sun came about. As mentioned earlier, in the section detailing the nebular theory, it was explained that as a direct result of a gravitational collapse of a section of the molecular cloud this precipitated the creation of the solar system (Boeyens, 2009: 493-499). A better explanation of this would be that as section of the nebula collapsed this produced a certain degree of angular momentum wherein the nebula actually began to spin faster as it collapsed in on itself. This spinning combined within the collapse produced a great deal of kinetic energy within the core of the molecular cloud until the result was a contraction of the center of the molecular cloud, which had now become a disc shaped object, into what is known as a proto-star, namely a star that has yet to have hydrogen fusion occur at its core (Boeyens, 2009: 493-499). Within 50 million years the internal temperature and pressure of the core itself was able to build to sufficient levels resulting in the start of hydrogen fusion marking the entry of the sun into its life as a main sequence star (Boeyens, 2009: 493-499)

Theory of Accretion

Accretion Model of Earth’s Creation

The theory of accretion is currently the most widely accepted theory proposing the creation of the planets, in it the theory indicates that the leftover material from the sun’s creation continued to spin around the sun slowly clumping together piece by piece until larger dust shaped particles were created (Ogihara et al., 2007: 522-530). Gradually these dust particles also began clumping together resulting in the creation of larger and larger objects until finally the entire solar system was composed of literally dozens of moon sized objects that crashed into each over a period of several million years (Ogihara et al., 2007: 522-530). It must be noted that the reason why such a process didn’t just create a system of bits and pieces of rock is due to the fact that these moon sized objects actually had viscous outer cores in the sense that their composition was similar to lava due to the high temperatures of the sun at the time and the process of accretion itself. As such when the objects collided what resulted was not a titanic clash that mutually shattered the objects but rather a process where both objects combined to form a larger structure or surfaces were “swapped” in the sense that certain parts of either proto-planet’s surface accreted to the colliding object (Ogihara et al., 2007: 522-530).

Creation of the Earth

Originally the Earth was a proto-planet no bigger than the moon yet over several million years the process of accretion was able to slowly build up the Earth to its present shape. It must be noted though that the early outer core of the planet was fluid in that due to the intense heat present at the time metals that had accumulated on the planet’s surface slowly submerged into the inner core creating the metallic core that is present today (Robin, 2008: 4061 -4075). Within 150 million years of the planet reaching its current mass the surface sufficiently cooled resulting in the creation of a primitive crust, yet unlike today the surface of the Earth is estimated by studies as being roughly 1600 degrees Celsius with numerous volcanoes dotting the landscape releasing gases into the atmosphere which formed the initial atmosphere of the planet which was kept in place by Earth’s inherent gravity (Robin, 2008: 4061 -4075).

Formation of the Oceans: Comet/Proto-planet Impact Theory

Most scientists agree that the presence of water on the Earth was the pivotal necessity necessary in order for life to start on the planet. When examining the process of Earth’s creation though there seems to be few indicators of water actually forming directly from the process of creation or within the Earth itself (Robin, 2008: 4061 -4075). One theory that attempts to explain this is the comet/proto-planet impact theory which states that proto-planets, planetoids and comets that were composed of ice were actually prevalent in the inner system during the later stages of the process of accretion. (Robin, 2008: 4061 -4075) As such as the Earth continued to orbit around the sun it supposedly impact millions of comets along with several icy proto-planets to create the water that can be seen in the oceans today. In fact, 4.4 billion years after the creation of the sun the Earth had actually sufficiently cooled enough to actually create clouds, rain, and the even oceans on the planets surface (Robin, 2008: 4061 -4075). This particular period marks the creation of the atmosphere that is present in the world today which is a combination of oxygen, carbon dioxide and other gases.

By the end of this paper it has become apparent that the process of creation of our solar system and even of our planet has been an accumulation of fortunate incidents that culminated in humanity evolving into its present state. When examining the theories explaining the creation of the molecular cloud, how Courtland (2010) presented the notion that the molecular cloud our present system came from originated from a rogue Super Massive star that coincidentally was shot out of its group by gravitational forces, that it was able to travel far enough to an area ideal enough for uninterrupted growth, that the creation of our planet was in the right place, at the right time with readily available water literally crashing into the planet in order to support life; a combination of all of these completely coincidental factors almost leads one to believe that the creation of humanity itself was no accident but on purpose. On the other hand there are quite literally billions upon billions of solar systems within the universe and it might actually be the case that the process that created the Earth is not so coincidental and that somewhere out there life similarly exists on thousands of planetary systems with the exact same composition as that of humanity yet far away enough that we cannot see the similarities at the present.

Solar System Essay

Table of Contents

The solar system essay is a remarkable and awe-inspiring essay about encompassing the Sun and its eight major planets, their moons, countless asteroids, and a myriad of comets. At its center is the Sun – a blazing ball of nuclear fusion that sustains life on Earth and all other celestial bodies nearby. Orbiting this source of energy are diverse planets, each with unique characteristics and mysteries waiting to be unraveled. From Mercury’s scorching inferno to Neptune’s icy desolation, our system showcases a wide range of environments.

Our home planet, Earth, stands out as the only known place in the universe where life thrives – making it particularly intriguing to both scientists and philosophers alike. The natural satellites of these planets – such as Earth’s Moon, Ganymede, and Titan – provide valuable insights into their parent bodies’ history and geology. In addition to these planets and their moons, the solar system also hosts numerous asteroids and comets which have played significant roles in shaping Earth’s past through impact events. Studying this vast system not only expands our understanding of the cosmos but also offers the potential for answers about the origin of life and habitable worlds beyond our own. As we continue exploring this wonderous celestial arrangement, it

It is a large celestial body that revolves in a fixed orbit around the Sun. It doesn’t have its lights and uses sunlight to reflect light. Because planets are closer to us, they don’t twinkle as stars. Mercury, Venus, Earth, and Mars remain in the inner solar system, while Jupiter, Saturn, Uranus, and Neptune are in the outer solar system.

Our Solar System

There are eight planets are divided into two groups: inner planets and outer planets. Inner planets, including Mercury, Venus, Earth, and Mars, are more minor and closer to the Sun. The remaining four planets – Jupiter, Saturn, Uranus, and Neptune – are much larger and often called Giant planets.

Our Solar System

The most minor planet in our solar system is Mercury, which is also closest to the Sun. Mercury’s geological features include lobed ridges and impact craters. Mercury has a very high surface temperature due to its proximity to the Sun. It can reach temperatures of 450 degrees Celsius during the daytime, but at night, Mercury is cold. Mercury’s diameter is 4,878 kilometres, and it lacks a natural satellite.

As well as being the hottest planet in our solar system, Venus has a toxic atmosphere always traps heat. Venus is also the brightest planet and can be seen from the ground. Venus has the same iron core as Earth and has a thick silicate layer surrounding it. The Venus planet has a diameter of 12,104 km and is similar to Mars. Astronomers have seen evidence of internal geological activity. As with Mars, Venus does not have any natural satellites like Earth.

During the Earth’s lifetime, life is possible because it is covered two-thirds with water. The atmosphere on Earth, which is rich in nitrogen and oxygen, makes it an ideal place for various flora and fauna to survive. Earth has a diameter of 12,760 km and one natural satellite, the moon. 

Often referred to as the Red Planet, Mars is the fourth planet from the Sun. This planet is cold and has similar geological features to Earth.This is the only reason why it has captured the interest of astronomers like no other planet. An ice cap has been discovered on this planet. 

Jupiter has a strong magnetic field and is primarily made up of helium and hydrogen. It also has a Great Red Spot and cloud bands. This giant storm is believed to have raged here for hundreds of years. There are 79 natural satellites on Jupiter, which is much more than there are on Earth and Mars combined. Jupiter has a diameter of 139,822 km.

As the sixth planet from the Sun, Saturn is also known for its ring system, composed primarily of ice and rock particles. Saturn’s atmosphere is quite like Jupiter’s because it is mostly made up of hydrogen and helium. Saturn has a diameter of 120,500 km and has 62 natural satellites, most of which are made up of ice. Saturn has fewer satellites than Jupiter.

The seventh planet from the Sun, Uranus, is the lightest. Uranus has a blue tint due to methane in its atmosphere. Its core is colder than the other giant planets, and it orbits on its side.

It is the coldest, Neptune is the largest and densest. Neptune has an atmosphere made up of helium, hydrogen, methane, and ammonia and has extremely strong winds. It is the only planet in our solar system that was discovered mathematically. Neptune has a diameter of 49,530 km and has 14 natural satellites, which is more than Earth or Mars combined.

Short Essay on Solar System and Planets (200 words)

The universe is massive. It is much bigger than we can imagine and our solar system is just a small part of it. Our solar system houses a big, bright star called the Sun. The Sun is a rich source of electromagnetic energy that it exudes in the form of light and heat. There are eight planets in our solar system namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These planets revolve around the sun in a fixed path referred to as the orbit. Several other smaller objects also move around the sun.

Many planets in our solar system have natural satellites called the moon. While Earth has one moon, Mars has two, Neptune has 14 moons, Uranus has 27 moons, Saturn has 62 moons and Jupiter has as many as 79 moons. Even the dwarf planet Pluto has 5 moons. Mercury and Venus, on the other hand, do not have any moon. Just as the planets move around the Sun in a fixed path, moons orbit around their respective planets.

In addition to the Sun, planets and moons, our solar system consists of several other celestial bodies called the comets, asteroids and meteoroids. While our solar system has only one star, many other solar systems are known to have at least two stars.

Essay on Solar System and Planets (300 words)

Our solar system was formed billions of years ago. It consists of numerous celestial bodies including planets, satellites, asteroids, comets, meteorites and a massive star. Our solar system forms a part of the Milky Way Galaxy. Various celestial bodies in our solar system revolve around the Sun directly or indirectly.

It is believed that around 4.6 billion years ago, the gravitational collapse of a giant interstellar molecular cloud gave shape to our solar system. Major part of the collapsing mass collated at the centre, that formed the Sun. The remaining mass flattened into a proto planetary disk and formed the planets, satellites and other objects in the solar system. Planet Jupiter, the biggest planet in our solar system, contains major chunk of the remaining mass.

Our solar system is believed to have evolved substantially since its inception. Many new moons have come into shape from the gases and dust around the planets. Several collisions among the celestial bodies have also occurred and still continue to occur thereby contributing to the evolution of the solar system.

For thousands of years astronomers believed that Earth was stationary and formed the centre of the universe. It was in the 18 th century that the astronomers accepted that Earth orbits around the Sun.

In 2 nd millennium BC, Mercury, Venus, Mars, Jupiter and Saturn were identified by ancient Babylonian astronomers. Later, Nicolaus Copernicus also identified them. Uranus was discovered by famous astronomer, Sir William Herschel in 1781. Neptune was discovered by English astronomer and mathematician, John Couch Adams in the year 1846. It was in the year 1930 that the ninth planet, Pluto was discovered. Astronomer Clyde Tombaugh discovered Pluto which is now identified as a dwarf planet.

The study of the universe and heavenly bodies is one of the most fascinating studies. Through continuous research, astronomers have found out several surprising facts about the universe and our solar system. Our solar system is ever evolving and newer facts are being discovered and studied by researchers year after year.

Essay on Solar System and Planets (400 words)

Celestial bodies are objects that naturally occur in the observable universe. These include the stars, natural satellites, planets, asteroids, galaxies, comets and meteorites. Our solar system consists of a Sun, eight planets their moons, five dwarf planets and asteroids among other celestial bodies. Brief information about each of the celestial bodies present in our solar system is given below.

The Sun is the only star on our solar system. It is stationary and the other objects in our solar system revolve around it. It is the most massive component of our solar system. Research states that it comprises of 99.86% of the entire mass of our solar system.

There are eight planets in the solar system. These are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The planets have been divided into two groups – Terrestrial Planets and Giant Planets. Planets vary based on their size, geological features, mass, number of satellites and various other factors. No traces of life have been found on any planet apart from Earth.

There are five dwarf planets in our solar system. These are Pluto, Ceres, Haumea, Eris and Makemake. While Ceres is situated in the asteroid belt others are located in the outer solar system. Dwarf planets are quite like the full size planets. The only difference is that the full size planets have cleared the objects in the area of their orbit whereas the dwarf planets have not.

Astronomers claim that there are six other objects in our solar system that are akin to the dwarf planets. These may be officially recognized as dwarf planets in the times to come.

There are a total of 193 moons in our solar system as per a research conducted in the year 2008. Out of these, 185 moons orbit around the full size planets and 8 moons revolve around the dwarf planets. Moons come in various sizes and shapes. They differ from each other in various ways. Most of the moons are airless. However, there are some that have atmosphere. Some even have hidden oceans. Each planet has different number of moons. Earth has just one moon while Jupiter has the highest number of moons. It has a total of 79 moons.  Moons orbit around their respective planets.

In addition to the aforementioned, there are many other celestial bodies in our solar system. These include the Interplanetary Medium, Kuiper Belt, Oort Cloud, asteroids and meteoroids. The Kuiper Belt and Oort Cloud comprise of billions of icy objects. Each celestial body in our solar system is unique with its own set of features.

Essay on Solar System and Planets (500 words)

Our solar system is huge but nothing compared to the size of the universe. The universe is humongous and is believed to encompass numerous solar systems consisting of several planets, stars and other heavenly bodies. The universe is all space and time and it is not possible to calculate its spatial size. The size of the observable universe is estimated to be 93 billion light years.

Research shows that just like our solar system there are numerous other solar systems in the universe. The universe consists of billions of galaxies. Each of these galaxies has uncountable stars and many of these stars are said to have solar systems of their own. The size of the stars, the number of planets, the geological features of the planets, the number and size of the natural satellites vary from solar system to solar system.

Our solar system is a part of the Milky Way Galaxy. The Milky Way Galaxy is huge. It has more than 100 billion stars. More than 2500 stars with planets orbiting around them have been discovered in the Milky Way Galaxy. The study in this field is going on constantly. There are numerous planetary systems that the scientists and astronomers are yet to discover.

Our solar system encompasses Sun which is a big ball of fire. Sun is stationary and forms the centre of our solar system. Eight planets namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune revolve around the Sun. Each of these planets move in a fixed path in its own set speed. The geological features of each of these planets are different. While Neptune is freezing cold, Venus is scorching hot. Similarly, while Jupiter is massively big, Mercury is comparatively very small in size. The planet is even smaller than some of the moons in our solar system. The atmosphere of each of the planets is different. Planets have been divided into two groups and the features of the planets within each group also vary vastly.

Earth is the only planet in our solar system which is known to have life. It is filled with vast oceans and gases such as oxygen and nitrogen that render life. Mars is said to share some similarities with Earth. Evidences of ice have been found on the planet. The planet is extremely cold and thus life there seems impossible. However, it is believed that the planet was once wet and warm and life existed here. Astronomers are studying this planet closely and have found many interesting facts about the same. These planets have different numbers of natural satellites.

Apart from this, there are five dwarf planets in our solar system. These are Ceres, Haumea, Makemake, Eris and Pluto. Earlier there were nine planets in our solar system and Pluto was one among them. However, it has now been termed as a dwarf planet.

The Universe is vast and there is a lot to study and discover. Scientists have studied our solar system deeply for centuries and are now moving beyond to study other solar systems and galaxies. A lot of interesting facts about this enchanting universe are likely to surface in the times to come.

Long Essay on Solar System and Planets (600 words)

Our solar system consists of eight planets that revolve around the Sun, which is central to our solar system. These planets have broadly been classified into two categories – inner planets and outer planets. There are four inner planets, Mercury, Venus, Earth and Mars. The inner planets are closer to the Sun and smaller in size as compared to the outer planets. These are also referred to as the Terrestrial planets. Jupiter, Saturn, Uranus and Neptune are termed as the outer planets. These are massive in size and are often referred to as Giant planets.

Here is brief information about each of these planets:

The smallest planet in our solar system, Mercury is also the closest to the Sun. Its geological features consist of lobed ridges and impact craters. Being closest to the Sun, Mercury’s temperature sores extremely high during the day time. It can go as high as 450 degree Celsius. Surprisingly, the nights here are freezing cold.

Mercury has a diameter of 4,878 km. It does not have any natural satellite.

Venus is said to be the hottest planet of our solar system. It has a toxic atmosphere that traps heat. It is also the brightest planet and is visible to the naked eye. It has a thick silicate layer around an iron core which is similar to that of Earth. Astronomers have seen traces of internal geological activity on this planet.

Venus has a diameter of 12,104 km. Just like Mars, Venus also does not have any natural satellite.

Earth is the largest inner planet. Two-third of this planet is covered with water. It is the only planet in our solar system where life is known to exist. Earth’s atmosphere, which is rich in nitrogen and oxygen, makes it fit for the survival of various species of flora and fauna. However, human activities are having negative impact on its atmosphere.

Earth has a diameter of 12,760 km. It has one natural satellite, the moon.

Mars, the fourth planet from Sun, is often referred to as the Red Planet. The iron oxide present on this planet gives it a reddish appeal. The planet is cold and has geological features similar to that of Earth. This is the reason why it has captured the interest of astronomers like no other planet. Traces of frozen ice caps have been found on the planet.

Mars has a diameter of 6,787 km and two natural satellites.

Jupiter is the largest planet in our solar system. It has a strong magnetic field. It largely consists of helium and hydrogen. It has a Great Red Spot and cloud bands. A giant storm is believed to have raged here for hundreds of years.

Jupiter has a diameter of 139,822 km and has as many as 79 natural satellites.

Saturn is known for its ring system. These rings are made of tiny particles of ice and rock. Its atmosphere is quite like that of Jupiter as it is also largely composed of hydrogen and helium.

Saturn has a diameter of 120,500 km. It has 62 natural satellites that are mainly composed of ice.

Uranus, the seventh planet from Sun, is the lightest of all the giant, outer planets. It has a blue tint which is because of the presence of Methane in the atmosphere. Its core is colder than the other giant planets. The planet orbits on its side.

Uranus has a diameter of 51,120 km and 27 natural satellites.

The last planet in our solar system, Neptune is also the coldest of all. It is around the same size as the Uranus but is much more massive and dense. Neptune’s atmosphere is composed of helium, hydrogen, methane and ammonia. It experiences extremely strong winds. It is the only planet in our solar system which is found by mathematical prediction.

Neptune has a diameter of 49,530 km. It has 14 natural satellites.

Scientists and astronomers have been studying our solar system for centuries and the findings are quite interesting. Various planets that form a part of our solar system have their own unique geological features and are different from each other in several ways.

The solar system is the gravitational bound system that comprises of sun and the objects that orbits the sun directly and indirectly. Its age is around 4.568 billion years. Its location of the solar system is local interstellar cloud. The solar system is tucked away with the corner of Milky Way at the distance of 30000 light years from the center of the galaxy.

The solar system consists of nine planets and these planets are known as the wanderer. Though stars do have the fixed position and the planet shift their position from one place to another but that too are not stationary.

The population of solar system consists of

  • Eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto)
  • Natural satellites (175 Planetary and 297 Minor Planetary)
  • Minor Planets 707664
  • Comets 3406
  • Identified satellites 19

The solar system was formed many billions years ago from the gravitational collapse of a giants interstellar molecule cloud. It is composed of sun, planets, comets, satellite, etc. it is primarily composed of rocks and metals. There are two giants available, that is, gas giants and ice giants.

Gas giants are mainly composed of hydrogen and helium whereas the ice giants are composed of volatile’s like water, ammonia and methane. Solar system is very huge and the Jupiter is the largest planet in the solar system.

History of Solar System

In the starting years, the concept of solar system was difficult to be understood but later after the detailed study in mathematics and physics in seventeenth century, solar system was accepted. Majorly the idea was accepted that the earth moves around sun.

Later the invention of telescope made it easier to discover the other planets and moons. The improvements in the telescope made for the investigation of geological phenomena such as mountains, clouds, dust storms and ice caps on other planets.

Types of Solar System

  • Inner Solar System : It comprises of terrestrial planets and the android belt. It is composed of silicates and metals. The objects of inner solar system are close to the sun and the inner planets have dense, rocky composition, few moons, and no ring system. There are metals in the crust like iron and nickel. These are generally four inner planets, that is, Mercury, Venus, Earth and Mars.
  • Outer Solar System : The outer solar system consists of the planets Jupiter, Saturn, Uranus and Neptune.

Generally everything in the solar system revolves around the sun as sun consists of the ninety eight percent of the materials available in the solar system. Sun is the head of solar family and compared to millions of other stars it is a medium sized star with average brightness but it appears to be larger and brighter because it is much more nearer to the earth than other stars.

The heat and light energy makes sun shine and the planets and other objects in the sky reflect a part of sunlight falling on them due to which they are visible to us. The earth too reflects the part of sunlight falling on it and that is the reason when we look earth from moon or other planets it looks bright.

The interaction between the earth and sun drives mainly four season, that is, winter, summer, autumn and spring. It also drives the ocean currents, climate, weather and radiation belts.

It is said that the larger an object more will be the gravity and because sun is having is having very powerful gravity; it attracts various objects near it. The planets orbit in the same direction goes in clock wise direction from North Pole and so the planets like Venus, Uranus and Pluto also rotate in the same direction.

In the solar system, earth is the only planet gifted that has life. Many researchers going on other planets in search of life like Mars but the results are not satisfactory. The men is moving ahead towards the advance technology that would definitely leads forward to quench the thirst for knowing the facts that remained unknown.

Life in our solar system.

Q. Pick TWO places in our solar system and tell me why you are hopeful there may be life there. Why?According to Patel (2021), although there is little likelihood of finding little green people in a corner of our solar system, there are a few candidates for astral bodies where it might be possible to find microbial life, such as bacteria. The first likely candidate is one of Neptunes moons, Triton. Although its surface is icy, mainly consisting of water nitrogen, and seemingly impossibly cold, there is some warmth generated by the gravitational pull between the planet and moon that could, at least theoretically warm its surface (Patel, 2021). A second candidate is Ceres, the smallest dwarf planet (Patel, 2021). This seems promising because there is the potential of actual water being present within the planet. Even if life is not found on the planets surface, it is possible that….

Solar Flares What Causes Solar Storms Why

Solar Flares What causes solar storms? Why should people nearly a hundred million miles away on Earth care so much about them? Massive explosions of electrified plasma from the sun are identified as Solar Storms but often they just cause a beautiful light show in the farthest points of the Northern and Southern Hemispheres. The reason why human beings need to understand and care about solar storms is that they have the potential to cause devastating effects on the planet Earth. Those effects include problems that may affect daily life such as knocking out satellites, blacking out power grids, and completely altering the atmosphere and climate. Scientists have gathered plenty of information over the years to explain Solar storms and have even built a system to protect the Earth's energy. However, the earth is still vulnerable to solar activity, much of which remains a mystery to science. Scientists are also uncertain….

Solar Thermal Systems According to

In this regard, some exceptions have been given to the insurance companies while the other companies should follow these principles. In the year 2005, the commercial sector of the United Kingdom spent $16,500 million for fossil fuels of 350,000 GWh. On the other hand, researchers have reported that a decline of energy consumption has been observed in the tertiary sector of the United Kingdom (Probst & oecker, 2011, pg 109-124). Hot water consumption Probst (2011) stated that hot water is consumed around three percent in industries and fifteen percent I the fossil energy. This shows that a total of 22,000GWh of hot water is consumed each year. The high and low temperature hot water from the hot water boilers is used in a number of things such as apace heating, washing and in some industrial processes. The direct and straight use of hot water is in washing. Modern hot water boilers are coming….

Solar Flares and How They Go on

solar flares and how they go on to cause global warming. Global warming has been an ongoing phenomenon and there are many reasons it has occurred. Apart from the green house effect, global warming could have been due to the solar flares that have occurred. Different researches and theories regarding this matter are discussed in the paper. Solar Flare Global warming is a phenomenon that has amazed and frightened everyone ever since it came into being. The consequences and end results of global warming is what goes on to alarm and frighten everyone on earth. If looked at it literally, global warming is basically in increase in the temperature of the Earth's atmosphere. This change and elevation has been occurring ever since the 19th century and is known to increase even more. The change in the global temperature is dangerous because it goes onto increase the sea levels and alterations precipitation,….

Solar Still Sustainable Development and

( Manion, 2002). The ethics of sustainable development in the sciences also includes the "precautionary principle." This refers to the view that, "When an activity raises threats of harm to human health and the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically" (Manion, 2002). In the light of the above brief overview of way that ethics and social responsibility have become part of the ethos of the contemporary scientific world, it becomes clear that a focus on technologies such as solar still production is one way in which engineers can enact their ethical and social responsibilities in this age. This project also takes into account the social and cultural needs and context of the people of the region, especially in areas where there is a lack of resources. From an ethical perspective, professional engineering organizations have made an important contribution and….

Solar Stills Limitations of Solar

A light insulation causes a reduction of 14.5% in the efficiency obtained with full insulation. The wind effect is much more limited. The increase of wind velocity from zero to 3.6 mph yielded a slight reduction (2%) in the still performance. Repeated tests have shown that the higher the operating temperature of the still, assuming insulation is equal, correlates with higher efficiency. For example, with each 6 degrees Celsius increase in ambient temperature, a still's output increases 7-8%. The application of this finding means that a still operating in a hot desert climate will produce typically as much as one-third more water than the same unit would produce in a cooler climate. Production of distilled water is also associated with the thermal efficiency of the still itself. Efficiency may range from 30 to 60%, depending on the construction of the still, the amount and type of insulation used, ambient temperatures, wind….

Photovoltaic Power System

Photovoltaic power system is a type of renewable energy that converts solar energy into solar photovoltaic electricity. Photovoltaic (PV) technology converts energy from the sunlight into the electricity. One of the advantages of the PV technology is that it is pollution free, and it is applicable with little maintenance. (EPIA 2008). Since sunlight is available free of charge, there has been an increase in the research and development (&D) to make the Photovoltaic energy available to all households and industry in the future. With the advantages derived from the PV energy systems, varieties of research have been launched at national and international laboratories focusing on the mass production of solar power at possible lower costs. (Dahl, 2005). In German, there are varieties of efforts in the development of PV technology. There has been an increase in the collaboration of government, university and the industry consortia in the development of Photovoltaic power….

BP Solar Ever-Increasing Technological Advances

It is yet to be seen whether alternative energy will eventually replace petroleum products or whether they will simply enhance the efficiency, cost effectiveness, and availability of energy in the future. BP's move into alternative energy will help it to position itself as a leader regardless of which direction the market decides to go. BP's move makes sense from many perspectives. It makes sense for a marketing perspective because it will help to improve BP's image to one that is more environmentally friendly and in line with current public consciousness. It will help it to make better use of natural resources from production to end use of all of its product lines. One advantage that BP has over many of the other companies entering into the alternative energy field is that it has experience in providing the needs of mass consumers. It understands the technical difficulties of supplying energy to millions….

It will also provide a specific organizational example of each type of organization, one for open systems and one for closed systems, and describe how these organizations meet the criteria of either the open or closed system perspective. There are vast differences in management and outcome between open and closed system models in organizations, and these differences are especially important to the criminal justice system. An open system allows for change and growth, while a closed system is less flexible and far more bureaucratic. The open and closed ideas of system models in organizations were originated by organizational experts obert L. Kahn and Daniel Katz in the 1960s. There are three basic system….

A favorite target for conspiracists today as well as in the past, a group of European intellectuals created the Order of the Illuminati in May 1776, in Bavaria, Germany, under the leadership of Adam Weishaupt (Atkins, 2002). In this regard, Stewart (2002) reports that, "The 'great' conspiracy organized in the last half of the eighteenth century through the efforts of a number of secret societies that were striving for a 'new order' of civilization to be governed by a small group of 'all-powerful rulers.' The most important of these societies, and the one to which all subsequent conspiracies could be traced, is the Illuminati founded in Bavaria on May 1, 1776 by Adam Weishaupt" (p. 424). According to Atkins, it was Weishaupt's fundamental and overriding goal to form a secret organization of elite members of Europe's leading citizens who could then strive to achieve the Enlightenment version of revolutionary….

Persistent Threats One of the biggest risks that companies face is advanced persistent threats. Advanced persistent threats can be very harmful to a company and can come in various forms as hackers have a variety of methods in their tool belt; however, on the receiving end, companies should be prepared for cyber attacks -- and yet they often are not, because of carelessness, neglect, lack of oversight, regulation, accountability, transparency, review, and an ability to conduct proper assessment. APTs are happening all the time and can be traced to origin locations all over the world (Norse, 2016). Cyber security should be therefore a number priority for any and all businesses that utilize information systems software and hardware.

Metric System -- One of the Reasons

Metric ystem -- One of the reasons measurement can be complicated is that there is more than one system in use. Based on the Ancient Roman system, the metric system is based on powers of 10; which is called decimalization. The metric system has been the preferred European and scientific method of measuring sine the 18th century, but is not part of the International ystem of Units, which is also standardized. Because the metric system is based on powers of 10, units are easier to align. cientists use the metric system as a way to have a common measurement between countries and over time. cientists use notation that makes it easier to conceptualize distances much easier, particularly when these distances are large.

As noted, the international operations will be controlled locally. The local partner will have significant input. Even when Solar Solutions has controlling interest, it is likely that a Saudi from the joint venture partner will run the subsidiary. The U.S. office is likely only to provide oversight. It is expected, however, that the U.S. will lend control techniques to the Saudi operation. The United States has robust accounting, auditing and control management techniques that can add value to the organization. In particular, managerial accounting techniques such as budgets and variance analysis will be utilized as control mechanisms for the subsidiary in Saudi Arabia. The company will need to develop a cross-national ethics and social responsibility code. These are values that will transcend borders and be an integral part of the culture of Solar Solutions. Thus, they need to apply to all of the company's operations. There is the risk that an….

Short Essay on Solar System and Planets (200 words)

The universe is massive. It is much bigger than we can imagine and our solar system is just a small part of it. Our solar system houses a big, bright star called the Sun. The Sun is a rich source of electromagnetic energy that it exudes in the form of light and heat. There are eight planets in our solar system namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These planets revolve around the sun in a fixed path referred to as the orbit. Several other smaller objects also move around the sun.

Many planets in our solar system have natural satellites called the moon. While Earth has one moon, Mars has two, Neptune has 14 moons, Uranus has 27 moons, Saturn has 62 moons and Jupiter has as many as 79 moons. Even the dwarf planet Pluto has 5 moons. Mercury and Venus, on the other hand, do not have any moon. Just as the planets move around the Sun in a fixed path, moons orbit around their respective planets.

In addition to the Sun, planets and moons, our solar system consists of several other celestial bodies called the comets, asteroids and meteoroids. While our solar system has only one star, many other solar systems are known to have at least two stars.

Essay on Solar System and Planets (300 words)

Introduction

Our solar system was formed billions of years ago. It consists of numerous celestial bodies including planets, satellites, asteroids, comets, meteorites and a massive star. Our solar system forms a part of the Milky Way Galaxy. Various celestial bodies in our solar system revolve around the Sun directly or indirectly.

The Formation of the Solar System

It is believed that around 4.6 billion years ago, the gravitational collapse of a giant interstellar molecular cloud gave shape to our solar system. Major part of the collapsing mass collated at the centre, that formed the Sun. The remaining mass flattened into a proto planetary disk and formed the planets, satellites and other objects in the solar system. Planet Jupiter, the biggest planet in our solar system, contains major chunk of the remaining mass.

Our solar system is believed to have evolved substantially since its inception. Many new moons have come into shape from the gases and dust around the planets. Several collisions among the celestial bodies have also occurred and still continue to occur thereby contributing to the evolution of the solar system.

The Discovery of Planets

For thousands of years astronomers believed that Earth was stationary and formed the centre of the universe. It was in the 18 th century that the astronomers accepted that Earth orbits around the Sun.

In 2 nd millennium BC, Mercury, Venus, Mars, Jupiter and Saturn were identified by ancient Babylonian astronomers. Later, Nicolaus Copernicus also identified them. Uranus was discovered by famous astronomer, Sir William Herschel in 1781. Neptune was discovered by English astronomer and mathematician, John Couch Adams in the year 1846. It was in the year 1930 that the ninth planet, Pluto was discovered. Astronomer Clyde Tombaugh discovered Pluto which is now identified as a dwarf planet.

The study of the universe and heavenly bodies is one of the most fascinating studies. Through continuous research, astronomers have found out several surprising facts about the universe and our solar system. Our solar system is ever evolving and newer facts are being discovered and studied by researchers year after year.

Essay on Solar System and Planets (400 words)

Celestial bodies are objects that naturally occur in the observable universe. These include the stars, natural satellites, planets, asteroids, galaxies, comets and meteorites. Our solar system consists of a Sun, eight planets their moons, five dwarf planets and asteroids among other celestial bodies. Brief information about each of the celestial bodies present in our solar system is given below.

The Sun is the only star on our solar system. It is stationary and the other objects in our solar system revolve around it. It is the most massive component of our solar system. Research states that it comprises of 99.86% of the entire mass of our solar system.

The Planets

There are eight planets in the solar system. These are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The planets have been divided into two groups – Terrestrial Planets and Giant Planets. Planets vary based on their size, geological features, mass, number of satellites and various other factors. No traces of life have been found on any planet apart from Earth.

The Dwarf Planets

There are five dwarf planets in our solar system. These are Pluto, Ceres, Haumea, Eris and Makemake. While Ceres is situated in the asteroid belt others are located in the outer solar system. Dwarf planets are quite like the full size planets. The only difference is that the full size planets have cleared the objects in the area of their orbit whereas the dwarf planets have not.

Astronomers claim that there are six other objects in our solar system that are akin to the dwarf planets. These may be officially recognized as dwarf planets in the times to come.

There are a total of 193 moons in our solar system as per a research conducted in the year 2008. Out of these, 185 moons orbit around the full size planets and 8 moons revolve around the dwarf planets. Moons come in various sizes and shapes. They differ from each other in various ways. Most of the moons are airless. However, there are some that have atmosphere. Some even have hidden oceans. Each planet has different number of moons. Earth has just one moon while Jupiter has the highest number of moons. It has a total of 79 moons.  Moons orbit around their respective planets.

In addition to the aforementioned, there are many other celestial bodies in our solar system. These include the Interplanetary Medium, Kuiper Belt, Oort Cloud, asteroids and meteoroids. The Kuiper Belt and Oort Cloud comprise of billions of icy objects. Each celestial body in our solar system is unique with its own set of features.

Our Solar System – A Small Part of the Universe

Our solar system is huge but nothing compared to the size of the universe. The universe is humongous and is believed to encompass numerous solar systems consisting of several planets, stars and other heavenly bodies. The universe is all space and time and it is not possible to calculate its spatial size. The size of the observable universe is estimated to be 93 billion light years.

The Galaxies and Solar Systems

Research shows that just like our solar system there are numerous other solar systems in the universe. The universe consists of billions of galaxies. Each of these galaxies has uncountable stars and many of these stars are said to have solar systems of their own. The size of the stars, the number of planets, the geological features of the planets, the number and size of the natural satellites vary from solar system to solar system.

Our solar system is a part of the Milky Way Galaxy. The Milky Way Galaxy is huge. It has more than 100 billion stars. More than 2500 stars with planets orbiting around them have been discovered in the Milky Way Galaxy. The study in this field is going on constantly. There are numerous planetary systems that the scientists and astronomers are yet to discover.

Our Solar System

Our solar system encompasses Sun which is a big ball of fire. Sun is stationary and forms the centre of our solar system. Eight planets namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune revolve around the Sun. Each of these planets move in a fixed path in its own set speed. The geological features of each of these planets are different. While Neptune is freezing cold, Venus is scorching hot. Similarly, while Jupiter is massively big, Mercury is comparatively very small in size. The planet is even smaller than some of the moons in our solar system. The atmosphere of each of the planets is different. Planets have been divided into two groups and the features of the planets within each group also vary vastly.

Earth is the only planet in our solar system which is known to have life. It is filled with vast oceans and gases such as oxygen and nitrogen that render life. Mars is said to share some similarities with Earth. Evidences of ice have been found on the planet. The planet is extremely cold and thus life there seems impossible. However, it is believed that the planet was once wet and warm and life existed here. Astronomers are studying this planet closely and have found many interesting facts about the same. These planets have different numbers of natural satellites.

Apart from this, there are five dwarf planets in our solar system. These are Ceres, Haumea, Makemake, Eris and Pluto. Earlier there were nine planets in our solar system and Pluto was one among them. However, it has now been termed as a dwarf planet.

The Universe is vast and there is a lot to study and discover. Scientists have studied our solar system deeply for centuries and are now moving beyond to study other solar systems and galaxies. A lot of interesting facts about this enchanting universe are likely to surface in the times to come.

Long Essay on Solar System and Planets (600 words)

Our solar system consists of eight planets that revolve around the Sun, which is central to our solar system. These planets have broadly been classified into two categories – inner planets and outer planets. There are four inner planets, Mercury, Venus, Earth and Mars. The inner planets are closer to the Sun and smaller in size as compared to the outer planets. These are also referred to as the Terrestrial planets. Jupiter, Saturn, Uranus and Neptune are termed as the outer planets. These are massive in size and are often referred to as Giant planets.

Here is brief information about each of these planets:

The smallest planet in our solar system, Mercury is also the closest to the Sun. Its geological features consist of lobed ridges and impact craters. Being closest to the Sun, Mercury’s temperature sores extremely high during the day time. It can go as high as 450 degree Celsius. Surprisingly, the nights here are freezing cold.

Mercury has a diameter of 4,878 km. It does not have any natural satellite.

Venus is said to be the hottest planet of our solar system. It has a toxic atmosphere that traps heat. It is also the brightest planet and is visible to the naked eye. It has a thick silicate layer around an iron core which is similar to that of Earth. Astronomers have seen traces of internal geological activity on this planet.

Venus has a diameter of 12,104 km. Just like Mars, Venus also does not have any natural satellite.

Earth is the largest inner planet. Two-third of this planet is covered with water. It is the only planet in our solar system where life is known to exist. Earth’s atmosphere, which is rich in nitrogen and oxygen, makes it fit for the survival of various species of flora and fauna. However, human activities are having negative impact on its atmosphere.

Earth has a diameter of 12,760 km. It has one natural satellite, the moon.

Mars, the fourth planet from Sun, is often referred to as the Red Planet. The iron oxide present on this planet gives it a reddish appeal. The planet is cold and has geological features similar to that of Earth. This is the reason why it has captured the interest of astronomers like no other planet. Traces of frozen ice caps have been found on the planet.

Mars has a diameter of 6,787 km and two natural satellites.

Jupiter is the largest planet in our solar system. It has a strong magnetic field. It largely consists of helium and hydrogen. It has a Great Red Spot and cloud bands. A giant storm is believed to have raged here for hundreds of years.

Jupiter has a diameter of 139,822 km and has as many as 79 natural satellites.

Saturn is known for its ring system. These rings are made of tiny particles of ice and rock. Its atmosphere is quite like that of Jupiter as it is also largely composed of hydrogen and helium.

Saturn has a diameter of 120,500 km. It has 62 natural satellites that are mainly composed of ice.

Uranus, the seventh planet from Sun, is the lightest of all the giant, outer planets. It has a blue tint which is because of the presence of Methane in the atmosphere. Its core is colder than the other giant planets. The planet orbits on its side.

Uranus has a diameter of 51,120 km and 27 natural satellites.

The last planet in our solar system, Neptune is also the coldest of all. It is around the same size as the Uranus but is much more massive and dense. Neptune’s atmosphere is composed of helium, hydrogen, methane and ammonia. It experiences extremely strong winds. It is the only planet in our solar system which is found by mathematical prediction.

Neptune has a diameter of 49,530 km. It has 14 natural satellites.

Scientists and astronomers have been studying our solar system for centuries and the findings are quite interesting. Various planets that form a part of our solar system have their own unique geological features and are different from each other in several ways.

  • 14 Science Projects and Lessons About the Solar System

Use these free STEM projects, lessons, and activities to help students get hands-on exploring and learning about solar system science.

Pocket solar system, play dough models of planets, and pool ball and marbles on a large piece of fabric to explore gravity to represent collection of STEM lessons and activities to teach about the solar system

The Earth, the Moon, the Sun, and space are concepts students identify early on. The names of the planets quickly follow, along with stars and the reality that the Sun, too, is a star and is the closest star to Earth. Students learn that the Earth is one of eight planets in our solar system, a group of planets that circle the Sun at a set pace and in a predictable elliptical pattern. How do you move beyond these basic concepts in teaching students about the solar system?

Despite early awareness of basic astronomy, science related to astronomy, the solar system, and even space beyond, can be difficult for students to comprehend because the scale is so large. Using models and hands-on systems helps students visualize and engage with questions about space and our solar system and brings to life an understanding of Earth as a single planet positioned in a solar system with other planets—and that our solar system is just one such system in the universe. As students model and explore our solar system, they build the framework on which they will expand their understanding of galaxies, our own and others, distances in space, the age of our solar system, the life cycle of stars, the composition of planets, and more.

The free STEM lessons and activities below are designed to help educators teach students about the solar system, including the order, size, position, and distances from the Sun of the planets. In learning about the solar system, students explore gravity; differences in the size, mass, and composition of planets and asteroids; orbits and how natural and manmade satellites work; and more.

The resources below have been grouped as follows:

Modeling the Planets in Our Solar System

Earth's rotation and orbit, gravity in our solar system, meteoroids & asteroids, other planets.

Note : Science Buddies Lesson Plans contain materials to support educators leading hands-on STEM learning with students. Lesson Plans offer NGSS alignment, contain background materials to boost teacher confidence, even in areas that may be new to them, and include supplemental resources like worksheets, videos, discussion questions, and assessment materials. Activities are simplified explorations that can be used in or out of the classroom. Student projects support students conducting independent science projects.

Lesson Plans and Activities to Teach About the Solar System

1. model the solar system.

Students learn early on the names of the planets (and maybe even a fun mnemonic device to help remember their order). But understanding the sizes of the planets and their distances from one another really helps bring understanding of our solar system into shape. The Make a Model of the Solar System lesson guides students in building a scale model of the solar system that represents the size of each planet as well as their distances from one another. Questions : Why are the planets spherical in shape? How big is the Sun in relation to the largest planets in the solar system? In the scale model, what object might be used for the Sun? ( Note : Short, separate activities are also available: Model the Distances between Planets in our Solar System ) and How Big Are the Planets in Our Solar System? ). The Worlds in Comparison lesson can also be used to create a model of the solar system.

2. A Fold-up Model Solar System

With the Pocket Solar System lesson, students use a single strip of paper to make a simple model of the solar system to visualize how much space exists between the planets. They'll be practicing fractions as they fold their model solar system, too! Questions : After making the fold-up model and looking at the planets all stretched out in a line to model the distances planets are from one another, what observations can you make about the planets that are closest to the Sun compared to the ones farther away? What is a dwarf planet? What is the largest dwarf planet in our solar system, and how far away is it from the Sun? What is an astronomical unit (AU)?

3. The Earth's Rotation

With the Kinesthetic Astronomy: Earth's Rotation lesson, students use kinesthetic techniques to better understand how the Earth moves, what the Earth's rotation means, and how the Earth's rotation on its axis differs from the Earth's orbit. In the activity, students use their bodies and movements to help them understand concepts (like which direction the Earth rotates and when sunset and sunrise occur) and locations (like where the equator is). Questions : Why do people in different locations, looking at the sky at the same time, see different things? What does the Earth's rotation have to do with days and nights on Earth?

4. Earth's Tilt and Seasons

With the Kinesthetic Astronomy: Longer Days, Shorter Nights lesson, students use a kinesthetic activity to better understand how the tilt of the Earth relates to changing patterns of light and the change in seasons. This lesson addresses common misconceptions about the relationship between the seasons and the Earth's position in relation to the Sun. Questions : At what time of the year is Earth closest to the Sun? How is the angle of the Sun's rays that reach the Earth related to the season?

Earth's seasons

5. An Earth Year

With the Kinesthetic Astronomy: The Meaning of a Year lesson, students use a kinesthetic activity to model the difference between Earth's daily rotation and year-long orbit around the Sun. Questions : What is the difference between an orbit and a rotation? Which direction does the Earth orbit the Sun? How long does a single orbit of the Earth around the Sun take?

Earth's orbit

6. Gravity and Escape Velocity

How does a spacecraft (or a planet) stay in orbit? Gravity is a key factor, but it isn't the only one! In the The Great Gravity Escape lesson, students explore the role of gravity and velocity in a spacecraft's orbit. In the hands-on activity, students spin water balloons attached to a length of string to investigate how the gravitational forces between two objects and the velocity of a traveling object balance to form an orbit. Questions : What happens if the velocity increases too much? What is escape velocity? Why is understanding escape velocity important for engineers developing spacecraft? How are the orbits of planets similar or different from the orbits of a spacecraft?

7. Modeling Gravity

With the Modeling Gravity lesson, students get hands-on with a large sheet, a billiard ball, and marbles to investigate how gravity works on Earth and in the solar system. With the Sun represented by the billiard ball and marbles representing the planets, students explore how the Sun's mass and gravitational force attracts objects. By experimenting with rolling the marbles from the edges of the model, students will see how sideways motion of the planets helps keep them in orbit around the Sun, rather than just being pulled to the Sun. Questions : Why do the planets in our solar system orbit the sun instead of flying off into space? What shape is the orbit of planets in our solar system? What does mass have to do with gravitational force? Why do moons orbit planets and not the Sun?

8. Gravity Assist Maneuvers

With the Slingshot to the Outer Planets lesson, students investigate how a gravity assist or "slingshot" maneuver can be used to help spacecraft reach distant planets. Students use magnets and ball bearings to simulate a planetary flyby and explore factors related to a successful slingshot maneuver. Questions : Why does it require so much energy for a spacecraft to reach the outer planets? What problem does a gravity assist maneuver help solve when thinking about interplanetary space travel? What is the deflection angle of a gravity assist maneuver?

9. Impact Craters

Some of the craters on planets and moons in the solar system are caused by meteorites that have crashed into the surface. In the Creating Craters activity, students make their own impact craters in a container of flour and investigate the relationship between the size and depth of an impact crater and the meteorite that caused it. For another exploration of crater formation, see the The Measure of Mercury: Analyzing Impact Craters on the Innermost Planet project. Remember! It is called a meteoroid while still in space, but a meteorite once it hits the surface. Questions : What are two variables that contribute to the size of an impact crater? How does the atmosphere on Earth change what happens to an impact crater over time? Why do not all meteoroids that enter Earth's atmosphere reach the surface?

10. Asteroids

There are millions of asteroids in space. These chunks of rock are remnants left over from the formation of the solar system, and scientists track and study asteroids for clues about the history of our solar system. The NASA Asteroid Database: What Can You Learn About Our Solar System? project guides students in using an asteroid database maintained by the National Aeronautics and Space Administration (NASA) and the Jet Propulsion Laboratory (JPL) to learn more about specific asteroids and their properties. Extend it! Asteroids may be useful for mining raw materials in space. Students can explore this possibility in the Asteroid Mining: Gold Rush in Space? project. Questions : What is the difference between a comet and an asteroid? Do asteroids orbit the Sun? What is an eccentric orbit? Where are most of the asteroids in our solar system located?

11. Saturn's Rings

Saturn's rings make it unique among the planets in the solar system. In the What Makes the Rings of Saturn? project, students learn more about these rings and investigate how the composition of the rings contributes to how they look. Questions : What are the rings of Saturn made of? Why do they look like rings?

12. Mars in Retrograde?

What does it mean when scientists talk about Mars being in retrograde? The Kinesthetic Astronomy: Mars Opposition Dance lesson helps students model the orbital speeds of Earth and Mars and learn what opposition , conjunction , and retrograde mean in astronomy. Questions : How often is Mars in retrograde? How does the orbital speed of other planets compare to that of Earth?

13. Getting to Mars

With the A Roundabout Way to Mars lesson, students use cardboard and string to learn about the orbits of Earth and Mars and explore the concept of orbit transfers, specifically, Hohmann transfers. Questions : How are Hohmann transfers different from other kinds of orbit transfers? What is a delta-v maneuver?

solar system and essay

14. Mars Elevator

Getting to Mars or to some other space destination takes a long time. Could some kind of space elevator work to make traveling between Earth and Mars faster? With the Space Elevator Problem Set activity, students investigate the idea of a space elevator by working through a math-based problem set. The activity requires understanding of Newton's laws of motion, Newton's law of universal gravitation, and algebra. Questions : What kind of material would be required for a space elevator cable? How do the requirements of a space elevator change depending on what celestial body is used as the anchor?

Worlds at the Far Reaches of the Solar System Could Support Life

T he small icy worlds on the edge of our solar system may be better contenders for life than we first thought, scientists have found.

The dwarf planets of Eris and Makemake, situated in the Kuiper Belt beyond the orbit of Neptune, may have geothermal activity beneath their surfaces, according to two new papers in the journal Icarus.

These geological processes were inferred by the discovery of recent methane isotopologues or isotopes—forms of methane differing by the number of neutrons in their nucleus—on the surface of Eris and Makemake. This marked the first time that these methane isotopologues have been discovered on objects beyond Neptune.

This implies that these dwarf planets might be warmer than first thought, and therefore more capable of hosting life.

Eris and Makemake, alongside Pluto and Haumea, are dwarf planets on the edge of the solar system. Dwarf planets are defined by having enough mass for their self-gravity to pull them into a roughly spherical shape, but they differ from full planets in that they have not cleared their orbital neighborhood of other debris.

Eris is the largest dwarf planet in the solar system, larger than Pluto, and orbits at an average distance of 6,289,000,000 miles away from the sun, about 68 times further out than the Earth. Its diameter is about 1,444 miles across, making it smaller than our own moon, which is 2,160 miles across. Eris orbits the sun once every 557 years, and was named for the ancient Greek goddess of discord and strife.

Makemake is the third-largest known dwarf planet in our solar system, after Pluto and Eris, with a diameter of 888 miles across. It takes about 309 years to orbit the sun. It was discovered in 2005 by the same team that discovered Eris in the same year, and was named after the creator of humanity and god of fertility in the mythology of the Rapa Nui people of Easter Island.

The papers reveal that Eris and Makemake have traces of geologically new methane on their surfaces that could only have gotten there as a result of geothermal activity. This suggests that the dwarf planets may be host to cryovolcanism, or even the presence of a hot rocky core.

"Eris and Makemake unveil a surprising narrative of internal dynamism," co-author of both papers, Noemí Pinilla-Alonso, a research professor at the University of Central Florida's Florida Space Institute, said in a statement. "The possibility of subsurface oceans and the revelation of rare, methane isotopologues CH3D and 13CH4 on these distant worlds challenge the conventional wisdom of primordial compositions in large trans-Neptunian Objects."

"This not only redefines our understanding of these icy worlds but also emphasizes the pivotal role of endogenic forces in shaping the outer solar system bodies," Pinilla-Alonso said.

This discovery was made using data gathered by the James Webb Space Telescope, which allowed the researchers to measure the composition of the surfaces of Eris and Makemake. In particular, they measured the ratio of deuterium or heavy hydrogen to hydrogen (D/H ratio) in the methane present. As deuterium is thought to have formed in the Big Bang, the D/H ratio can reveal the origin and history of chemicals containing hydrogen.

"The moderate D/H ratio we observed with JWST belies the presence of primordial methane on an ancient surface," Christopher Glein, co-author of both papers, and a planetary scientist and geochemist at the Southwest Research Institute, said in the statement. "Primordial methane would have a much higher D/H ratio. Instead, the D/H ratio points to geochemical origins for methane produced in the deep interior."

The researchers also found evidence in the carbon isotope ratio (13C/12C) of recent resurfacing of the chemicals on the dwarf planets, further indicating geological activity. This could point to there being liquid water present deep under the surfaces of the planets.

"If Eris and Makemake hosted, or perhaps could still host warm, or even hot, geochemistry in their rocky cores, cryovolcanic processes could then deliver methane to the surfaces of the planets, perhaps in geologically recent times," Will Grundy, an astronomer at Lowell Observatory and co-author of the March 2024 issue study, said in the statement.

This therefore could make Eris and Makemake contenders for the presence of life.

"The measured D/H ratios on Eris and Makemake are much lower than the D/H ratio observed in primordial surfaces in the solar system, for example, the comet 67P/Churyumov-Gerasimenko, recently visited by a spacecraft," Pinilla-Alonso said.

"The distinct isotopic ratios suggest that the hydrogen atoms in the methane on Eris and Makemake likely originated from water, indicating geochemical processes in their warm or even hot deep interiors," she said. "These findings, with implications for habitability considerations, highlight JWST's pivotal role."

Solar System is bigger than we thought. New Horizons makes surprise discovery

The spacecraft revealed that the kuiper belt – the vast, distant outer zone of our solar system populated by hundreds of thousands of icy, rocky planetary building blocks - has an extended region..

Listen to Story

Solar system with kuiper belt

  • Kuiper Belt is the vast, distant outer zone of our solar system
  • It is similar to the asteroid belt but is located much farther away from Sun
  • New Horizons is expected to operate through the 2040s

The Solar System is a big place, spread over billions of kilometers in each direction from Earth, and it does not end at Pluto. Instead, there is a much wider field of rocks and ice known as the Kuiper belt that encircles it.

Nasa's New Horizons spacecraft has now revealed signs that this boundary of the solar system is much bigger than what scientists had initially estimated.

Kuiper Belt

Astronomers are still discovering strange things in space, and the latest is something they’ve named the Radcliffe Wave . This wave-shaped chain of star-forming clouds is the largest coherent structure ever seen in our galaxy — 9,000 light-years from end to end, stretching across the night sky from Canis Major to Cygnus , with Orion in between.

Now it turns out the Radcliffe Wave is actually waving. So claims a paper published Tuesday in the journal Nature.

The star-forming clouds are rising far above the plane of the galaxy and then back down again. This kind of oscillation is known as a traveling wave, which is akin to sports fans “doing the wave” by popping up from their seats in a synchronized round-the-stadium pattern.

“This issue of the wave — you can find papers that hint at it in the past — but it’s nailed down now. This is a brick in the wall and it’s not coming out,” said Bob Benjamin, an astronomer at the University of Wisconsin at Whitewater who was not part of this new research. “This newest paper is a really neat step in understanding the origin of this structure.”

This structure is within our galaxy and virtually right next door. It’s within spitting distance — if you could spit 500 light-years.

The story has another twist: It appears that our solar system passed through the Radcliffe Wave about 13 million years ago. And that might have been an interesting time for life on Earth. These star-forming regions have more than their fair share of exploding stars.

“Thirteen million years ago, we think we could have passed through a festival of supernovae going off,” said study co-author Catherine Zucker, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics.

Motion in the Milky Way

Until just a few years ago, no one recognized that the many star-forming clouds relatively near the sun were part of a coherent structure. That’s because astronomers can see distant galaxies better than the one that surrounds us, the Milky Way. There is no telescope out there in intergalactic space, a couple million light-years away, obtaining beautiful images of the entirety of our galaxy. (If there is, it’s not one of ours.)

“It’s really hard to see what the structure of your hand is if you put it very close to your face,” explains Alyssa Goodman, an astronomy professor at Harvard and co-author of the new report. “We don’t get to fly outside the galaxy.”

Astronomers have known for a century that the Milky Way is just one of many galaxies. They have also known that ours is a large spiral galaxy that’s much like the neighboring Andromeda Galaxy.

The cloudlike ribbon of milky light that you can see on a clear night — and which, as Galileo discovered four centuries ago with a telescope, is filled with individual stars — is an edge-on view of the plane of our home galaxy. The galaxy is a pancake-like disk, made from a relatively thick batter, if you will. We’re right there in the mix, and we can see stars in all directions that are part of the pancake.

But only in recent years has it been possible to create a precise three-dimensional map of stars and gas in our sector of the galaxy. This is in part thanks to the European Space Agency’s Gaia spacecraft, which is designed to measure with unprecedented precision the distances to millions of stars in our galaxy and their motion relative to each other.

The “fixed stars,” as astronomers and sailors call them, are not actually just sitting there in deep space. Everything’s moving. Our solar system makes one orbit of the center of the galaxy over the course of about 226 million Earth-years .

Using Gaia data, Joao Alves, Zucker, Goodman and six colleagues described the Radcliffe Wave in a 2020 paper in Nature. They named it in honor of early 20th-century female astronomers associated with Radcliffe College, including Radcliffe graduate Henrietta Leavitt, who discovered that the periodic brightening of certain stars encoded information about their distance from Earth.

That breakthrough was critical to the discovery that the intriguing “spiral nebulae” seen through telescopes are actually structures outside the Milky Way — distinct galaxies in a universe even more vast than previously imagined.

The Radcliffe Wave appears to be the backbone (or “ gas reservoir ,” as a 2022 paper put it) of the spiral arm of our galaxy closest to our sun, known as the Orion Arm, or Local Arm. Additional updates from Gaia allowed scientists to create theoretical models to track the motion of star clusters within the wave, revealing its undulations.

The big question now: Why is the Radcliffe Wave waving?

“Who ordered that?” Goodman asked.

Something clearly happened to disturb our galactic neighborhood and impose disorder on the heavens. One possibility is that something — perhaps a dwarf galaxy — came crashing into the Milky Way and caused a big splash, and the wave is a ripple effect.

Another possibility is that a sequence of supernovae — explosions of stars emitting powerful bursts of radiation — shook things up. Or it could be a combination of factors.

“It might be that stars exploded as supernovae, and pushed the gas and the dust out of the galaxy plane,” said Ralf Konietzka, a PhD candidate at Harvard and lead author of the new paper. This wavelike pattern will disappear in a few tens of millions of years, he said.

Earth’s ride through the wave

There’s more digging to be done here, Zucker and her colleagues say — and more scientific papers are in the offing. There could be signs in the geological record of Earth being affected by supernova explosions in that long-ago transit through the Radcliffe Wave.

Earth has a magnetic field that helps protect it from potentially harmful radiation coming from the sun. And the sun’s solar wind creates a great protective bubble around the entire solar system that helps protect us from dangerous particles racing through space from other points in the galaxy.

But here’s where “interstellar weather” complicates the picture. A nearby supernova could have compressed that bubble, called the heliosphere, to the point that our planet was fully exposed to the interstellar medium.

The next step is to look into the geological record for signs that Earth was pelted with an isotope of iron consistent with exposure to a supernova about 13 million years ago. And then cross-tab that with anything interesting in the biological record.

“Galaxies may be even more dynamic than we previously thought,” Konietzka said.

Scientists say 2 solar system dwarf planets may harbor underground oceans

Two dwarf planets within our solar system, named Eris and Makemake, might exhibit enough geothermal activity to maintain oceans of liquid water within, according to modeling that describes new observations made with the James Webb Space Telescope.

"We see some interesting signs of hot times in cool places," said Christopher Glein, a planetary geochemist from Texas' Southwest Research Institute, in a statement .

Found deep in the Kuiper Belt , Eris is the icy world that, when it was discovered in January 2005, threw Pluto 's status in the solar system into crisis. Just 44 kilometers (27 miles) smaller than Pluto but 25% more massive thanks to a greater concentration of rock in its core, Eris became the prototype dwarf planet. Pluto was inevitably forced to follow suit. Makemake (pronounced " Mah-kay-Mah-kay ") was spotted two months after Eris, and at 1430 km (888 miles) across is about 1000 km (about 600 miles) smaller than Eris and Pluto.

Their great distance from the Sun —– Eris is currently 14.4 billion kilometers (8.9 billion miles) away  and Makemake is 7.7 billion kilometers (4.8 billion miles) away – means little is known about these faraway dwarf planets .

However, recent observations with the James Webb Space Telescope have shed new light on the worlds, finding a surprising origin for the frozen methane-ice on their surface.

"We found evidence pointing to thermal processes producing methane from within Eris and Makemake," said Glein.

Methane is what's known as a hydrocarbon, in that it is formed from a mixture of hydrogen and carbon atoms (specifically, one carbon atom and four hydrogen atoms.) Those atoms can come in different flavors, or "isotopes," containing the same number of protons but different numbers of neutrons .

If the methane on these dwarf planets' surfaces had been accreted from the primordial planet-forming disk that existed around the young sun 4.5 billion years ago, they would contain a certain isotopic ratio between two isotopes of hydrogen — regular hydrogen, with one proton and zero neutrons, and deuterium, with one proton and one neutron. The hydrogen isotope ratio measured by the JWST, however, is different to the ratio that would be expected if the methane were primordial, as we see on most comets .

"The deuterium/hydrogen ratio points to geochemical origins for methane produced in the deep interior," said Glein. "Our data suggest elevated temperatures in the rocky cores of these worlds so that methane can be cooked up. Molecular nitrogen could be produced as well, and we see it on Eris."

In other words, hydrothermal reactions, or metamorphic activity which refers to heat and pressure acting on rocks, must have produced the methane deep inside Eris and Makemake. Then,  that methane must've made its way to the surface via outgassing, or even volcanism.

For methane to form in this manner, a temperature in excess of 150 degrees Celsius (about 300 degrees Fahrenheit) is required. These temperatures could only come from radioactive isotopes present within the rocky cores of each dwarf planet giving off heat as the isotopes decay.

"Hot cores could also point to potential sources of liquid water beneath their icy surface," said Glein, raising the possibility that Eris and Makemake could contain possibly habitable oceans.

The outgassing of methane onto the surface may have been happening until (geologically) recently according to another isotope ratio, between carbon-12, which has 6 protons and 6 neutrons, and carbon-13, which has 6 protons and 7 neutrons.)

"If Eris and Makemake hosted, or perhaps could still host warm, or even hot, geochemistry in their rocky cores, cryovolcanic processes could then deliver methane to the surfaces of these planets, perhaps in geologically recent times," said Will Grundy of Lowell Observatory , who led the initial JWST observations. "We found a carbon isotope ratio that suggests relatively recent resurfacing."

Intriguingly, the models developed to describe the formation and outgassing of methane on Eris and Makemake could also apply to Saturn 's moon Titan . Research published earlier this month indicated that methane and other carbon-based molecules important for life might not be able to reach Titan's subsurface ocean after hanging out on the surface for a bit,e where hydrocarbons are plentiful. This called into question the presumed possible habitability of Titan's ocean. However, if methane and other gases can form geothermally within the rocky core of Titan, as they do on Eris and Makemake, then Titan's ocean could get its supply of carbon chemistry from within the planet rather than from its surface.

The results of the methane observations on Eris and Makemake are described in a paper published in the April 2024 issue of the journal Icarus .

If you’ve ever wanted to experience a total solar eclipse from the sky, Delta has you covered this April.

The airline is offering a special flight from Austin to Detroit on April 8, 2024, specifically for umbraphiles to be able to spend as much time as possible directly within the path of totality.

Delta flight 1218 will be specifically operated on an A220-300, which will offer especially premium viewing due to the aircraft’s extra-large windows. The flight will depart from Austin at 12:15 p.m. CT and land in Detroit at 4:20 p.m. ET — timed to give those on board the best chance of safely viewing the solar eclipse at its peak.*

“This flight is the result of significant collaboration and exemplifies the close teamwork Delta is known for — from selecting an aircraft with larger windows to determining the exact departure time from Austin and the experiences at the gate and in the air,” said Eric Beck, Managing Director of Domestic Network Planning. “Thanks to teams across the company, the idea of viewing a total eclipse from the air will become a reality for our customers.”

Even if you aren’t on this special flight, Delta travelers will also have prime eclipse-viewing opportunities on five additional routes on April 8, so don’t forget your protective viewing glasses if you’re on these flights:

  • DL 5699, DTW-HPN, 2:59 pm EST departure, ERJ-175
  • DL 924, LAX-DFW, 8:40 am PST departure, A320
  • DL 2869, LAX-SAT, 9:00 am PST departure, A319
  • DL 1001, SLC-SAT, 10:08 am MST departure, A220-300
  • DL 1683, SLC-AUS, 9:55 am MST departure, A320

And for those who would rather catch the solar event from the ground, Delta flies to many destinations that are within the path of totality, including AUS, San Antonio (SAT), and Little Rock, Ark. (LIT).

“The April 8 eclipse is the last total eclipse we’ll see over North America until 2044,” said Warren Weston, Delta Air Lines Lead Meteorologist. “This eclipse will last more than twice as long as the one that occurred in 2017, and the path is nearly twice as wide.”

*While Delta flight plans have been designed to maximize time within the path of totality, this is subject to change due to factors outside of Delta’s control such as weather and air traffic control that could impact timing and aircraft.
