The Coma Cluster (also known as Abell 1656) is a large cluster of galaxies composed of more than 1,000 identified galaxies, located in the constellation Coma Berenices, within a few degrees of the north galactic pole on the sky. Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster. Its ten brightest spiral galaxies have apparent magnitudes of 12-14. The central region is dominated by two supergiant elliptical galaxies: NGC 4874 and NGC 4889. The vast majority of the galaxies that lie in the central portion of the Coma Cluster are ellipticals, either dwarf or giant. The cluster's mean distance from Earth is 99 Mpc (321 million light years).
