Messier 60 or M60, also known as NGC 4649, is an elliptical galaxy approximately 57[4] million light-years away in the equatorial constellation of Virgo. Together with NGC 4647, it forms a pair known as Arp 116.[8] Messier 60 and nearby elliptical galaxy Messier 59 were discovered by Johann Gottfried Koehler in April 1779, observing a comet in the same part of the sky.[9] Charles Messier added both to his catalogue about three days after this.[9]
