NGC 4002 is a lenticular galaxy located 310 million light-years away[2] in the constellation Leo. It was discovered on April 10, 1785, by astronomer William Herschel.[3] NGC 4002 forms a pair with the galaxy NGC 4003 known as [T2015] nest 102886,[4] and is part of the Coma Supercluster.[5][6]
NGC 4002 is a quasar candidate according to Simbad,[7] and is host to a supermassive black hole with an estimated mass of 9 × 108 M☉.[8]
