Bre'el IV moon

The Bre'el IV moon was an asteroidal moon in orbit of Bre'el IV in the Bre'el planetary system.

In 2366, the moon began to fall out of orbit, threatening the planet. Q theorized that this was caused by a large celestial object passing at near right-angles to the plane of the star system, likely a black hole. The USS Enterprise (NCC-1701-D) made several attempts to return the moon to its proper orbit, but was unable to do so. Disaster was ultimately averted by Q when he returned the moon to its proper placement.
