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]

Contents

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]
