NGC 2748 is a spiral galaxy in the northern circumpolar constellation of Camelopardalis, located at a distance of 61.3 megalight-years from the Milky Way. It was discovered September 2, 1828 by British astronomer John Herschel.

Characteristics

The morphological classification of SAbc indicates NGC 2748 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. 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.

NGC 2655 group

NGC 2748 is part of the NGC 2655 group (also known as LGG 165). Other galaxies in this group are NGC 2591 [fr], NGC 2715, UGC 4466 [d], UGC 4701 [d], and UGC 4714 [d].

Supernovae and Luminous Red Nova

Four supernovae and one luminous red nova have been observed in NGC 2748.
