Lenticular galaxy in the constellation Leo
NGC 4003 is abarred lenticular galaxy located 305 millionlight-years away[ 3] constellation Leo . It was discovered on April 10, 1785, by astronomerWilliam Herschel .[ 4] NGC 4002 known as [T2015] nest 102886,[ 5] 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 withNGC 4002 .[ 4]
NGC 4003 is aLINER galaxy ,[ 7] [ 8] [ 7] supermassive black hole with an estimated mass of 9.6 × 108 M ☉ [ 9]
