Is it possible for a moon to have a moon?
I see. What kind of conditions would need to be present for a submoon to form?
A submoon would require a stable orbit around the moon and a distance that is not too close to prevent it from being destroyed by tidal forces, but not too far away to keep it captured by the moon's gravity. Furthermore, the moon itself would need to be in a stable orbit around its planet.
