NGC 4889, also known as Caldwell 35, is a supergiant^[4] class-4 elliptical galaxy, the brightest within the Coma cluster and a Caldwell object in the constellation Coma Berenices. It shines at magnitude +11.4. Its celestial coordinates are RA 13h00.1m, DEC +27°59'. It is located near the G-class naked-eye star Beta Comae Berenices, the galaxy NGC 4874 (also in the Coma Cluster^[4]), and the North Galactic Pole. It lies roughly 308 million light-years away.^[2] The main cluster is retreating at roughly 7,000 kilometres per second (4,300 mi/s)^[5], while NGC 4889 itself is retreating at 6,495 kilometres per second (4,036 mi/s).
