NGC 4458 is an elliptical galaxy located about 54 million light-years away[3][4] in the constellation of Virgo.[5] It was discovered by astronomer William Herschel on April 12, 1784.[6] NGC 4458 is a member of Markarian's Chain which is part of the Virgo Cluster.[7] It is in a pair with the galaxy NGC 4461.[8] NGC 4458 and NGC 4461 are interacting with each other.[9]

NGC 4458 may have a supermassive black hole with an estimated mass of 200 million Suns (2×108 M☉).[2]
