NGC 4003 is a barred lenticular galaxy located 305 million light-years away[3] in the constellation Leo. It was discovered on April 10, 1785, by astronomer William Herschel.[4] NGC 4003 forms a pair with the galaxy NGC 4002 known as [T2015] nest 102886,[5] and is part of the Coma Supercluster.[6]

NGC 4003 has a triple-ringed structure. It has a nucleus with a ringlike structure with dust lanes inside it, a strong bar surrounded by a second ring which is connected to broad spiral arms, and a nearly complete outer ring. It is thought the structure of NGC 4003 is a result of past interaction with NGC 4002.[4]

NGC 4003 is a LINER galaxy,[7][8] with star formation dominating its nucleus,[7] and is host to a supermassive black hole with an estimated mass of 9.6 × 108 M☉.[9]
