This is one of the episodes where Bajor is depicted as having several moons with apparently normal atmospheres and gravity. But if the moons were that large/dense/massive, they would not simply be orbiting Bajor. Bajor and the moons would be orbiting each other in a kind of cluster, which might have resulted in occasional collisions in the past.

When Mullibok's door closes you can see the wire used to hold it open.
