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
−0.08×108 M☉).

Supernova

One supernova has been observed in NGC 4564: SN 1961H (type unknown, mag. 11.2) was discovered by Italian amateur astronomer Giuliano Romano on 2 May 1961. A spectrum taken indicated that it was probably of Type I.
