NGC 4459 is a lenticular galaxy located about 50 million light-years away[2] in the constellation of Coma Berenices.[3] NGC 4459 is also classified as a LINER galaxy.[2] NGC 4459 was discovered by astronomer William Herschel on January 14, 1787.[4] NGC 4459 is a member of the Virgo Cluster.[5]
Physical characteristics
Dust disk
NGC 4459 has a central flocculent dust disk that surrounds an inner ring.[6][7] Also, there appears to be evidence of ongoing star formation in the disk .[7]
Super massive black hole
NGC 4459 has a supermassive black hole with an estimated mass of roughly 70 million suns (7×107 M☉). Its diameter is estimated to be around 2.87 astronomical units[8] (266.4 million mi).[9]
