The M74 Group (also known as the NGC 628 Group) is a small group of galaxies in the constellation Pisces. The face-on spiral galaxy M74 (NGC 628) is the brightest galaxy within the group. Other members include the peculiar spiral galaxy NGC 660 and several smaller irregular galaxies .[1][2][3] The M74 Group is one of many galaxy groups that lie within the Virgo Supercluster.[4][5]
