NGC 5004 is a 13.1 mag bright, lens-shaped galaxy of the Hubble-type S0 in the constellation Haar der Berenike in the northern sky . It is an estimated 316 million light years from the Milky Way , about 130,000 ly in diameter, and belongs to the Coma Galaxy Cluster .
The supernova SN 1976A was observed here.
The object was discovered on March 13, 1785 by Wilhelm Herschel with an 18.7-inch reflecting telescope, who described it as "vF, vS, lE".
Also called NGC 5004 A , it forms an optical triple constellation with the non-NGC objects IC 4210 (also called NGC 5004 B ) and PGC 45757 (also called NGC 5004 C ).
