Question

Define earth and planets.​

Answer 1

Earth is the third planet from the Sun and the only astronomical object known to harbor life. A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
