This is a list of unnamed moons.
Ajir IX moon
The Drenar system contained at least two planets with moons. Drenar IV had three moons. When surveyed by USS Voyager in the year 2371, Captain Kathryn Janeway found it unusual for a planet this close to its star to have moons. Drenar VI was a class J gas giant. Its largest moon was used by Voyager to gather resources through its Bussard ramscoops to produce deuterium fuel. (VOY novel: Ghost of a Chance)
Edge of Klingon space
In a star system on the edge of Klingon space, a large planet was surrounded by an asteroid field and at least one moon. In the year 2409, the moon was detected and dismissed by Jurlek's bird-of-prey during their search for iridium-rich asteroids. (STO - Tour of Duty mission: "Your New Command")
Rakon IV moon
This unnamed moon of Rakon IV served as a meeting place for a group of temporal scientists led by Professor Vard. This meeting led to the moon becoming a battlefield in the Temporal Cold War as various factions tried to destroy the scientists. (DTI novel: Watching the Clock)
