NGC 4564 is an elliptical galaxy located about 57 million light-years away in the constellation Virgo. NGC 4564 was discovered by astronomer William Herschel on March 15, 1784. The galaxy is also a member of the Virgo Cluster.
NGC 4564 has an estimated population of 213 ± 31 globular clusters. It is the host of a supermassive black hole with an estimated mass of about 56 million suns (0.56+0.03
−0.08×10 M☉).
Supernova
One supernova has been observed in NGC 4564: SN 1961H (type unknown, mag. 11.2) was discovered by Romano on 2 May 1961.
