Damn! You're right! I'll need to fix that, thanks.
most orbits are ellipses, with the major body at one focus. further, even given a circular orbit, the minor body does not orbit the center of the major body, but a common barycenter with it. </vulcan>
but yeah, the planet should at least be on the plane of the moon's orbit.
