Essay on The Solar System

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

Indeed, most of the problem is that there is no formal definition of a planet. Furthermore, it is very difficult to invent one that would allow the solar system to contain all nine planets. I suggest that for an object to be classified as a planet, it must embody three characteristics. It must be in orbit around a star (thus removing the larger satellites from contention), it must be too small to generate heat by nuclear

The sun is a star that is made up of hydrogen gas. The sun is unlike other stars that we see in the sky because the sun delivers energy and radiation that allows to living things to exist. Also, the sun is much closer than the other stars in the sky.

Then red dwarf star that was discovered by Michal Gillion and his team with the spencer telescope. Once they discovered this star that is a lot small and colder than our sun, it allowed them to get a vision of the seven planets. The star is about 40 light years away. There are not 3 or four planets but there are 7 earth like planets.

Mercury, named after the Roman God of Thievery, Commerce, and Travel, is the first planet from the Sun. It is unique because it shows at both morning rise and evening set of the sun. It is rocky, heavily cratered, covered in boulders, and also pulverized dust. The majority of it's surface bears a strong resemblance to that of Earth's moon. It's lack of atmosphere causes wild temperature fluctuations. Temperatures can range from 90 kelvin to 700 kelvin thus creating a planet, from all observations, that cannot sustain life--it is geologically dead. Mercury also has a magnetic field generated by the planet's core that can deflect solar wind and which has a magnetosphere that changes. This was surprising for such a slow rotating planet--one that rotates completely every 88 Earth days.

Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky (“Astronomy for Kids”). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979,

i. The difference between a star and a planet is that a star undergoes a nuclear reaction that burns hydrogen at their core, planets do not. In order to burn hydrogen at the core an object needs to have a very large mass, like that of stars. There is also a difference in the way that stars and planets form. Stars form when a cloud of gas collapses under the pressure of gravity. Planets, however, form when material in the disk around a pre-existing star beings to condense. Other major differences is that the stars have their own light and planets do not. Planets are small in size compared to stars, also stars are at a constant point and planets revolve around the sun.

At first glance, it might seem like Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto barely have anything in common, but looking at it closer will help one realize that they have plenty similarities. An example is all of the planets revolves around the Sun. This fact is, of course, obvious, but it surely is one similarity the diverse planets has together. Not only that but the planets also a body that orbits the sun. although Pluto is not as big as the other planets, it was still large enough to have its own gravity, which is what makes it round and somewhat spherical.

Mercury is the first planet. It was named after the Roman god of thievery. It also only takes 59 Earth days to rotate.

With The Planets, Op. 32, composed 1914-1916, Gustav Holst incorporates a wide array of cultural and scientific references to create musical characters for each of the planets in our solar system. The scientific connection is immediately clear simply by looking at how Holst chose to order the movements. While he does not specifically place the planets in order of distance from the sun, they still follow a pattern that clearly references their positions in space. Mars, Venus, and Mercury open the suite, being numbers 3, 2, and 1 from the sun (neglecting to count Earth, which does not appear). Following this are Jupiter, Saturn, Uranus, and Neptune, being numbers 4, 5, 6, and 7 in order. While an awareness of their scientific positions is

Mercury which is the planet that is closest to the sun is the first planet I will discuss. Mercury is the smallest of the inner

Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.

The terrestrial planets are Mercury, Venus, Earth, and Mars. These four planets are the planets that are closest to the sun. Terrestrial means earthlike; therefore, these planets are all earthlike because they have a solid ground. The terrestrial planets are the middle school years. The knowledge learned here orbits the sun. If the knowledge learned at the sun is not retained, a student may have a

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.

     Have you ever heard of a solar flare? A solar flare exists after a sunspot has existed for a long time and the magnetic lines of force usually become jumbled. As a result of this jumbling, magnetic energy is stored in the Corona (region of atmosphere above the chromosphere). The energy may be released in a spectacular discharge, which is a solar flare. A solar flare can be as wide as 367,000 miles and as high 500,000 miles out into space. A solar flare is nothing more than helium erupting from the sun like a volcano.
