How Does a Planet Differ from a Star?

Answer

A star contains much more mass than a planet, enough that gravitational forces have compressed the matter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out. A planet orbits a star in a regular manner. The sum of a star and its orbiting planets is called a Solar System. Stars are always much bigger than planets. Also, their content is different. Stars are made of mostly hydrogen, which they push together to form helium.
