Messier 60 taken on March 23, 2015 (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. NGC 4647 appears approximately 2′ away 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. The pair together is collectively known as Arp 116.
