NGC 4692 is an elliptical galaxy located 370 million light-years away[2] in the constellation Coma Berenices. It was discovered on April 11, 1785, by astronomer William Herschel.[3] NGC 4692 is the brightest member 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]
According to Harold Corwin, NGC 4702 is equal to NGC 4692, with the former designation simply being a reobservation of NGC 4692.[6]
NGC 4692 is host to a supermassive black hole with an estimated mass of 9 × 108 M☉.[7]
