This article is focused on the planets of the solar system that are grouped into different classifications. The planets are generally divided into two parts i.e. “The Giant Planets” and “The Terrestrial Planets”. Mercury, Venus, Earth, and Mars are the four inner planets of terrestrial planets. On the other hand, Jupiter, Saturn, Uranus, and Neptune are the four giant planets.
About the solar system:
The solar system is the whole collection of all the planets, moons, meteoroids, asteroids, and comets, all spin around the sun that is the central star. There are a total 8 planets along with approx 210 planetary satellites in the solar system and these are the main objects of the solar system. All of these objects contain a broad range of compositions, huge sizes, and high temperatures. Some of the objects are active with heavy storms, changing weather patterns. On the other hand, some of the planets are dead, dusty, and make lump rocks. The most important thing is, they all are united with the gravity of the sun. Hydrogen and helium are the primary components of planets Jupiter and Saturn.
According to ancient astronomers, the brightest planets or objects of the solar system are easily visible without a telescope.
As two categories of planets are “The Giant Planets” and “The Terrestrial Planets”, the sizes of the planets of “The Terrestrial Planets” category are generally small in size. Those planets are Mercury, Venus, the Earth, and Mars. They are mainly rocky in nature or composition. On the other side, “The Giant Planets” i.e. Jupiter, Saturn, Uranus, and Neptune; are very giant in size. They are the largest planets in the solar system. They contain a high range of “hydrogen ices and gases”. “Pluto” considered a dwarf planet that does not fall in any of the above categories. This is a fully icy planet with a size smaller than the Earth’s Moon.
Relatively, some of the inner planets lack ring systems and solid surfaces with no moons or very few moons.
The Earth, the only astronomical object known to harbour life where the atmosphere of the Earth consists of cxygen and nitrogen. The earth was developed based on four stages. The first stage among all the stages is “Differentiation”. Throughout this stage, the light elements rose to the top to form the outside portion and heavy elements went down at the centre of the Earth. The next stage is “Cratering”, which makes a solid surface of the Earth. The third one is “Flooding”, through this stage; the lava and other heat elements heated the Earth due to the lava flows and formed Oceans in basins and rain. The last stage is “Slow Surface Evolution”. Every “Terrestrial Planets” went through these four stages to develop themselves.
In the solar system, there are several satellites or moons. As per the research of many scientists, this total number of moons and satellites of the respective planets are discussed below:
Mars has 2 satellites; Jupiter has a total of 79 satellites. Among them, 53 are the most confirmed satellites and the rest of the 26 satellites are the provisional satellites of Jupiter. In the case of Satur, it has a total of 82 satellites, among which 53 are the confirmed satellites and 29 others are the provisional satellites. Uranus has a total of 27 satellites and Neptune has 14 satellites. The planet of life that is Earth has 1 satellite that is the Moon. As per the scientists, the Earth’s Moon was formed at the time when a huge body of Mars hit the Earth and ejected a huge amount of materials from the Earth into orbit.
The Moons are also called the “Natural Satellite”. It comes in different shapes and sizes with different types of solid bodies. This Moon is not man-made, this is a natural component. The Mars has 2 natural satellites i.e. Moon. The dwarf planet that is Pluto, it has 5 numbers of satellites.
The above whole discussion is the small elaboration of the planets and the other objects or components of the solar system.
This assignment mainly focused on the different types of categories of planets in the solar system. The planets that are the main components in the solar system are discussed in the discussion section broadly. Moreover, the researcher has discussed components of the planets along with the stages of the development of the planets. There is also a short description of the satellites or Moon that are also important objectives or components of the Solar system. The paper also tried to reveal the facts that arose after the research of the respective planetary scientists. Life apart from the Earth in the solar system; is also shortly discussed throughout the discussion.
