Ja, well, why not? The moon co-orbits the sun along with the earth. The moon's orbit is everywhere concave, which is to say, when the moon is between the sun and the earth, it falls toward the sun, as viewed by a sun-stationary observer. I think it is proper to refer to the moon as a planet. It is a small but respectable size for a planet, not much different from Mercury and probably larger than Pluto, which was recently downgraded, by the way... spike
