What is a Planet?

A planet is a celestial body that orbits around the Sun or around another star. They can be either rocky or gaseous in composition. Another definition by the IAU states that a planet must do three things, 1. Orbit a star, 2. Be large enough to become round, under it's own gravity. and 3. It must be big enough to clear objects of a similiar size away from its orbit.
