A planet is an object massive enough to form the shape of a sphere under it's own gravitational pull, and also it would be capable of clearing it's orbit of other like-sized bodies. Look up the brand-new definition of planet from the International Astronomical Union.

A planet is a world. After the sun was formed a great cloud of gas, lots of matter was left over. This whirled around the new star, in time forming a system of nine planets, which we call the solar system. Planets have orbits. All the planets are held in their orbits around the sun by the sun's gravitational force. Planets have gravity. All planets have their own gravity. The bigger the planet, the bigger its gravitational pull. The nine planets in our solar system are nine different worlds.
