M86 lies in the heart of the Virgo Cluster of galaxies.
The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Million light years away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies, the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (containing our Milky Way galaxy) is a member.
On my picture you could see M86 as the largest galaxy but you could observe more than a hundred galaxies more, on the annotated version you could find all the information.
