Arp 116 (APG 116) is a pair of interacting galaxies composed of elliptical galaxy Messier 60 and spiral galaxy NGC 4647, located in the Virgo Constellation, lying about 60 million light years away, in the Virgo Cluster, at right ascension 12h 43m 36.1s declination +11° 34′ 02″ .[1][2][3] Interaction between the two galaxies has just begun, with initial findings of tidal interaction being found in 2012.[1] With an apparent separation between the galaxies of 2'.5, the optical discs of the two galaxies overlap.[4]
