Gamma Trianguli VI

Gamma Trianguli VI was a class M planet in the Alpha Quadrant. It was the home world of a humanoid race, controlled by a computer called Vaal for approximately 10,000 years.

Gamma Trianguli VI was visited by the USS Enterprise in 2267, at which time Captain James T. Kirk destroyed Vaal. (TOS episode: "The Apple")
