Mettula Orionsis
From Tardis Wiki, the free Doctor Who reference
Metulla Orionsis was a star system that contained the planet Traken, the capitol of the Traken Union. It is possible that either Metulla Orionsis was one of the systems of the Union or if it was the entire Union. At least three planets were seen to make up the system (one being Traken). (DW: The Keeper of Traken)
In 1981, a temporary wave of entropy swept across part of the universe, destroying Metulla Orionsis in the process. (DW: Logopolis)
