The International Astronomical Union (IAU) which decides these kinds of things has decided that a planet is a celestial body that --
1) is in orbit around the Sun;
2) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape and;
3)has cleared the neighborhood around its orbit
