NGC 3937 is an elliptical[3][4] or a lenticular galaxy[5][3][4] located about 310 million light-years away[5] in the constellation Leo. It was discovered by astronomer William Herschel on April 27, 1785[6] and is classified as a radio galaxy.[3][7]

NGC 3937 is host to supermassive black hole with an estimated mass of 3.7 × 109 M☉.[8]

NGC 3937 Group

NGC 3937 is the brightest[9] member of the NGC 3937 Group, which is part of the Coma Supercluster.[10][11][12][13] The group has a velocity dispersion of 306 km/s. Other members of the group are NGC 3910, NGC 3929, NGC 3940, NGC 3943, NGC 3947, NGC 3954, with NGC 3919 having an uncertain membership.[10]
