Galaxy Seven

Galaxy Seven was one of the satellite galaxies of Mutter's Spiral.

History
At some point in humanity's future, the tourist board renamed a number of galaxies. These included the Sculptor Dwarf galaxy, which became Galaxy Seven.


 * This may mean that the similarly named Galaxy 4 was also renamed by the same tourist board.

The Doctor visited the planet Arcopolis while he was travelling alone. This planet was located deep within this Galaxy Seven. (NSA: The Eyeless)
