NGC 4331 is an irregular galaxy located 74 million light-years away [2] in the constellation Draco. The galaxy was discovered by astronomer William Herschel on December 12, 1797. [3] The galaxy is host to a black hole with an estimated mass of 4.6×105 solar masses. [4]

NGC 4331 is a member of the NGC 4291 Group, which also contains the active galaxy NGC 4319 [5] [6] [7] [8] and is an X-ray bright member of the group. [9] The NGC 4291 Group is located within the Canes Venatici-Camelopardalis Cloud, [5] which lies in the First Upper Plane of the Virgo Supercluster. [6]
