But to be considered as a planet it have to have a spherical shape... The only "difference" I see between planets and moons (besides that a moon has not to apply the spherical shape), is the orbit, a planet orbits around a sun (maybe we could say, sun or suns), and a moon orbits around a planet.
 
Best regards,
Leo
