The universe consists of more than 500 solar systems as of now or as of our limited knowledge on the universe. Our solar system is present inside the Milkyway galaxy. The Milkyway galaxy is called so because the Romans named it as they found the earth’s skyline at night to resemble that of a band and a patch of milk. The solar system is the most important part of our Milkyway galaxy. According to experts and astronomers, the solar system is the only planetary body in the universe that supports life. And earth, a part of the solar system, is the only planet that supports life in the universe. But this can easily be false since man has not discovered all the aspects of our universe.
Solar systems consist of eight planets, which are Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus and Neptune. Pluto was also a planet but it was derecognized a few years ago because of its size. The main criteria for being a planet are it should orbit around the sun, it should have sufficient mass to assume hydrostatic equilibrium and it should have a clearly defined neighborhood around its orbit. Pluto failed in the second criterion. But Pluto is known as a dwarf planet. All these decisions of naming, recognizing and derecognizing of planetary objects are taken by the International Astronomical Union (IAU). Basically, IAU is an international body that consists of astronomers and scientists all across the world with the main objective and goal of promoting and safeguarding the astronomical sciences in every sphere, through collective international cooperation.
Each planet present in the solar systems revolves around the sun inside their own orbits at their own speed. This is an essential criterion to be declared as a planet in the solar system.
Each of the planets that we mentioned has its own characteristics, which is given below
