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
