Short description: Galaxy in the constellation Centaurus

NGC 5011 is an elliptical galaxy in the constellation of Centaurus.^[2] It was discovered on 3 June 1834 by John Herschel.^[4] It was described as "pretty bright, considerably small, round, among 4 stars" by John Louis Emil Dreyer, the compiler of the New General Catalogue.^[4]

Optical companions

Several galaxies are not physically associated with NGC 5011, but appear close to NGC 5011 in the night sky. PGC 45847 is a spiral galaxy that is also known as NGC 5011A.^[5] PGC 45918 is a lenticular galaxy^[6] some 156 million light-years away from the Earth, in the Centaurus Cluster, and is designated NGC 5011B.^[7] PGC 45917 is a dwarf galaxy, also designated NGC 5011C.^[8]^[7] Although NGC 5011B and 5011C appear close together, they are no signs of them interacting.^[7] NGC 5011C is actually much closer and is in the Centaurus A/M83 Group, at 13 million light years away.^[7]
