NGC 4889, also Caldwell 35, is a supergiant elliptical galaxy in the constellation Coma Berenices. It is located near the naked-eye G-class star Beta Comae Berenices, the galaxy NGC 4874, and the North Galactic Pole.
With an apparent Magnitude of 11.4, NGC 4889 is the brightest within the Coma cluster of galaxies. This cluster contains more than 1000 galaxies, and lies roughly 250 million light-years away. It is so large that light takes several million years to travel from one side to the other. The main cluster is receding at roughly 7000 km/s, while NGC 4889 is retreating at 6495 km/s.
Although NGC 4889 has apparent diameter of only 3.0', the two brightest members, NGC 4889 and NGC 4874 are both classified as supergiant elliptical galaxies. With diameters of 330,000 light years and 260,000 light years, respectively, both NGC 4889 and NGC 4874 are far larger than our own Milky Way galaxy.
