NGC 7320
NGC 7320 is a spiral galaxy in Stephan's Quintet. However, it is not an actual member of the galaxy group, but a much closer line-of-sight galaxy at a distance of about 40 million light years, the same as the nearby NGC 7331. Other galaxies of Stephan's Quintet are some 300 million light-years distant.
