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]
