M86
The Virgo Cluster is a cluster of galaxies at a distance of approximately 59 Mly away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies. The cluster is an aggregrate of at least three separate subclumps centered on the galaxies M87, M86, and M49. Of the three subclumps, the one centered on M87 is the dominant one, with a mass of approximately 1014 solar masses, which is approximately an order of magnitude larger than the other two subclumps. The Virgo cluster lies within the Local Supercluster, and its gravitational effects slow down the nearby galaxies.
