Arp 116, GC 3182.
Messier 60, also known as NGC 4649, is an elliptical galaxy approximately 55 million light-years away in the constellation Virgo. It is part of a pair of galaxies known as Arp 116 with NGC 4647.
Messier 60 and the nearby galaxy Messier 59 were both discovered by Johann Gottfried Koehler in April 1779 during observations of a comet in the same part of the sky. Charles Messier listed both in the Messier Catalogue about three days after Koehler's discovery.
Overlapping galaxy NGC 4647
NGC 4647 appears approximately 2′.5 from Messier 60; the optical disks of the two galaxies overlap. Although this overlap suggests that the galaxies are interacting, photographic images of the two galaxies do not reveal any evidence for gravitational interactions between the two galaxies as would be suggested if the two galaxies were physically close to each other. This suggests that the galaxies are at different distances and are only weakly interacting if at all. However, recent studies by the Hubble Space Telescope show indications that tidal interactions may have just begun. The pair together is collectively known as Arp 116 (APG 116).
Virgo Cluster membership
M60 is the third-brightest giant elliptical galaxy of the Virgo cluster of galaxies, and is the dominant member of a subcluster of four galaxies, which is the closest-known isolated compact group of galaxies.
