Detailed explanation-1: -A planet is a large object that orbits a star. To be a planet, an object must be massive enough for gravity to have squeezed it into a spherical, or round, shape, .
Detailed explanation-2: -Most asteroids are irregularly shaped, though a few are nearly spherical, and they are often pitted or cratered. As they revolve around the Sun in elliptical orbits, the asteroids also rotate, sometimes quite erratically, tumbling as they go.
Detailed explanation-3: -Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330, 000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume.
Detailed explanation-4: -The sun not only has a much larger radius than Earth-it is also much more massive. The sun’s mass is more than 333, 000 times that of Earth, and contains about 99.8 percent of all of the mass in the entire solar system! The sun is made up of a blazing combination of gases.
