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]
