The NGC 7331 group is a collection of galaxies located in the constellation Pegasus. It is centered around the spiral galaxy NGC 7331, which is often compared to the Milky Way due to its similar structure. This group includes several other galaxies, such as NGC 7323, NGC 7320, and NGC 7320c, which are part of the same cosmic neighborhood. The NGC 7331 group is approximately 50 million light-years away from Earth. It is notable for its relatively bright galaxies and is often studied to understand galaxy formation and evolution. The group is also part of a larger structure known as the Sloan Great Wall.
