NGC 7331 - The Deer Lick Galaxy Group

NGC 7331, also known as The Deer Lick Galaxy Group is a grouping of a large unbarred spiral galaxy similar in size to the Milky Way Galaxy and four smaller galxies all located in the constellation of Pegasus. It was originally thought the the four smaller galaxies were satellite galaxies of NGC 7331. However, NGC 7331 is located about 40 Million light-years from Earth, while the four smaller galaxies are actually much more distant, ranging from 300 Million to 350 Million light-years from Earth.
