NGC 3951 is a spiral galaxy located 300 million light-years away[2] in the constellation Leo. It was discovered on April 10, 1785, by astronomer William Herschel.[3] NGC 3951 is a member of a group of 5 galaxies known as [T2015] nest 100412 or the UGC 6846 Group,[4] which is part of the Coma Supercluster.[5] Other members of the group are UGC 6846, UGC 6855, IC 739, and 2MASX J11543515+2352505.[4]
NGC 3951 is a LINER galaxy,[6] host to a supermassive black hole with an estimated mass of 1 × 108 M☉.[7]
