Gallifrey

Gallifrey is a fictional planet in the long-running British science fiction television series Doctor Who and is the home world of the Doctor and the Time Lords. It is located in a binary star system (Gridlock) within the constellation of Kasterborous (Pyramids of Mars, Attack of the Cybermen and Voyage of the Damned), at "galactic coordinates ten-zero-eleven-zero-zero by zero-two from galactic zero centre" (Pyramids of Mars (1975), Full Circle (1980) and partially in "The Family of Blood" (2007)), which is some 250 million light years away from Earth (as stated in the 1996 Doctor Who television movie). This would put it far outside our Milky Way galaxy, which is about a hundred thousand light years in diameter, and indeed outside the Local Group and even the Virgo Supercluster; however, at this distance it would still be within the Pisces-Cetus Supercluster Complex.
