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]
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]
