Roche Limit

The Roche Limit was a principle in astronomy that was, according to Alex Bannen, "No moon can exist within a certain distance of its parent planet without breaking apart due to gravitational stress." Due to the intervention of the Angels, Moloch orbited Lucifer within its Roche Limit, but had not broken up, baffling the Project Eden team. (PROSE: Lucifer Rising)
