Out of the three, planets are far larger than asteroids or comets. The technical definition of a planet is a cosmic mass that's large enough to be rounded by its own gravity, but not so large that gravity causes extreme pressures to heat the object and turn it into a nuclear furnace (a sun).
Asteroids and comets, on the other hand, are basically chunks of matter (rock and possibly ice and gases) that remain, compared to planets, irregularly shaped.
