NGC 4312 is an edge-on unbarred spiral galaxy[3] located about 55 million light-years away[2] in the constellation Coma Berenices. It was discovered by astronomer William Herschel on January 14, 1787.[4] NGC 4312 is a member of the Virgo Cluster[5][6][7] and is a LINER galaxy.[8]

It has undergone ram-pressure stripping in the past.[9]

Black Hole

NGC 4312 may harbor an intermediate-mass black hole with an estimated mass ranging from 10,000 (1*10^4) to 300,000 (3*10^5) solar masses.[10]
