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☉).[8]

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