The definition is not always very clear. For our Solar System, the definition is used that a planet orbits the Sun, and has "cleared its neighborhood", meaning that there are no other orbits of comparable size crossing its orbit. Note that this definition makes no direct reference to the planet's size! There is not yet a clear definition for other solar systems; this will need to be clarified, once we start discovering smaller and smaller objects.
