Planets are the celestial bodies found in space. Planets usually revolve around a star or a similar body, and they have a gravitational aura of their own.
It’s a round shape body and orbits around the sun in an elliptical manner. This whole setup is known as the solar system, and on a bigger picture, it’s a Milky Way galaxy.
The gravitational pull is strong enough so that it moves in a spherical shape. It orbits around a star.
Names of Planets:
There are up to nine known planets in the solar system, and names are as under:
- Mercury nearest to the sun
- Venus: It spins slowly in the opposite direction to all the planets.
- Earth: Life is only found on this planet and third planet from the sun.
