NGC 2748 is a spiral galaxy in the northern circumpolar constellation of Camelopardalis,[6] located at a distance of 61.3 megalight-years from the Milky Way.[3] It was discovered September 2, 1828 by John Herschel.[6] The morphological classification of SAbc[5] indicates this is an unbarred spiral with moderate to loosely-wound spiral arms. It is a disk-like peculiar galaxy with a stellar shell that is rotating about the main galactic axis. This shell was most likely formed through the capture and disruption of a dwarf companion.[7] The galactic nucleus likely contains a supermassive black hole with a mass of 4.4+3.5
−3.6×107 M☉, or 44 million times the mass of the Sun.[5]
