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][5] The galaxy is also a member of the Virgo Cluster.[6][7]
NGC 4564 has an estimated population of 213 ± 31 globular clusters.[8] 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☉).[9]
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.[10][11] A spectrum taken indicated that it was probably of Type I.[10]
