Bre'el IV moon

The Bre'el IV moon, also known as the Bre'el satellite, was the asteroidal moon of Bre'el IV. This moon was located somewhere in the Alpha or Beta Quadrant.

The moon had a minimum orbit distance of 50,032 kilometers, a maximum distance of 50,059 kilometers, a mean orbital inclination of 0.025 degrees, and an average orbital period of 746 minutes.

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-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.
