NGC 4673 is an elliptical galaxy located 317 million light-years away[2] in the constellation Coma Berenices. It was discovered on April 6, 1785, by astronomer William Herschel.[3] NGC 4673 part of a group of 11 galaxies, known as [T2015] nest 100111, which is also known as the NGC 4692 Group[4] and is part of the Coma Supercluster.[5][6]

NGC 4673 is host to a supermassive black hole with an estimated mass of 7.2 × 108 M☉,[7] and a population of 750 globular clusters.[8]
