Detria VI was the sixth planet in the Detrian system. This planet was classified as a gas giant.

In 2369, Detria VI collided with another, smaller gas giant in the system, Detria II; through a fusion reaction, this collision gave birth to a new star. (TNG: "Ship in a Bottle")

The planet was identified "Deltria VI" on an LCARS display of the collision.
