The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Mly (16.5 ± 0.1 Mpc) [2] away in the Virgo constellation. Comprising approximately 1,300 (and possibly up to 2,000) member galaxies, [ 3 ] the cluster forms the heart of the larger Virgo Supercluster , of which the Local Group (containing the Milky Way galaxy ) is a member.

The number density of galaxies in the LS falls off with the square of the distance from its center near the Virgo Cluster, suggesting that this cluster is not randomly located. Overall, the vast majority of the luminous galaxies (less than absolute magnitude −13) are concentrated in a small number of clouds (groups of galaxy clusters ).
M87 is the largest galaxy in the Virgo cluster, and is at a distance of 60 Mly from Earth (redshift 0.0035). It is a major radio source, partially due to its jet of electrons being flung out of the galaxy by its central supermassive black hole.
M87 is near (or at) the center of the Virgo Cluster, [44] a closely compacted structure of about 2,000 galaxies. [127] This forms the core of the larger Virgo Supercluster , of which the Local Group (including the Milky Way) is an outlying member. [ 7 ]

In the nucleus lies a nuclear star cluster which is 2.2 arcseconds across. [7] NGC 4775 is a member of the NGC 4697 Group, also known as LGG 314. [8] [9] Other members of the group include NGC 4697, NGC 4731, NGC 4941, NGC 4951, NGC 4948, and NGC 4958. [9] It is part of a Virgo II Groups, a chain of groups extending from the Virgo Cluster.

NGC 4550 is a barred lenticular galaxy located in the constellation of Virgo that can be seen with amateur telescopes. It lies at a distance of 50 million light-years (15.5 mega parsecs) from the Milky Way and is a member of the Virgo Cluster. [2]
