The Coma I Group is a group of galaxies[3][1] located about 14.5 Mpc (47.3 Mly)[7] away in the constellation Coma Berenices. The brightest member of the group is NGC 4725. The Coma I Group is rich in spiral galaxies while containing few elliptical and lenticular galaxies. Coma I lies in the foreground of the more distant Coma and Leo clusters and is located within the Virgo Supercluster.[3]
The Coma I Group is currently infalling into the Virgo Cluster and will eventually merge with it.[10]
