NGC 4564 is an elliptical galaxy located about 57 million light-years away [2] in the constellation Virgo. [3] NGC 4564 was discovered by astronomer William Herschel on March 15, 1784. [4] The galaxy is also a member of the Virgo Cluster. [5] [6]
NGC 4564 has an estimated population of 213 ± 31
globular clusters.
[7] 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☉).

On May 2, 1961, a Type Ia supernova designated as SN 1961H was discovered in NGC 4564. [9] [10]
