NGC 4221 is a barred lenticular galaxy located about 75.9 million light-years (23.28 megaparsecs) away [3] in the constellation of Draco. It was discovered on April 3, 1832, by the astronomer John Herschel. [5] NGC 4221 is notable for having an outer ring [6] that surrounds the inner barred central region of the galaxy. [5]
NGC 4221 is a member of the NGC 4256 Group, [4] [7] [8] which lies in the upper plane of the Virgo Supercluster. [4]
