Koo was a star system, located somewhere in the space of the galaxy's Alpha or Beta Quadrants. (ST video game: Starfleet Command, ST video game: Starfleet Command II: Empires at War, ST video game: Starfleet Command: Orion Pirates, ST video game: Starfleet Command III)
- No history or specifics are established for this location in Starfleet Command III, as its name was randomly selected for a system on the game map by the game software. Most of the systems in the game are named for real stars, and with the theme being modern astronomy, this one is possibly named for contemporary astronomer David Koo.
