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]
