NGC 4558 is a barred lenticular galaxy[2] located 360 million light-years away[3] in the constellation Coma Berenices. It was discovered on April 19, 1827, by astronomer John Herschel.[4] NGC 4558 is a member of a group of 12 galaxies known as [T2015] nest 100082, or the NGC 4555 Group,[5] and is part of the Coma Supercluster.[6]
NGC 4558 is host to a supermassive black hole with an estimated mass of 7.3 × 108 M☉.[7]
