NGC 4213 is a elliptical galaxy located 344 million light-years away[2] in the constellation Coma Berenices. It was discovered on April 10, 1785, by astronomer William Herschel.[3] NGC 4213 is a member of the NGC 4213 Group,[4][5][6] which is part of the Coma Supercluster.[4][5] Other members of the group are IC 772, IC 3075, IC 3089, 2MASX J12140497+2404021, and 2MFGC 9641.[6]
NGC 4213 has a supermassive black hole with an estimated mass of 9.7 × 108 M☉.[7]
