Solar system

We all know that the solar system consists of 9 planets, Asteroids belt, and comets. But have we ever taken effort to read the details of the planets. Probably most of us will say NO. So here are the details of all the plants in the solar system. Here you will the diameter of each planet, their mass and the rotation period and revolution periods around the sun.
