NGC 4874 is a supergiant elliptical galaxy in the constellation of Coma Berenices. It was discovered on 11 April 1785 by German-British astronomer William Herschel, who catalogued it as a bright patch of nebulous feature. The second-brightest galaxy within the northern Coma Cluster, it is located at a distance of about 97 megaparsecs (316,000,000 light-years) from Earth.
