NGC 2655 is a lenticular galaxy in the constellation Camelopardalis. It is at a distance of 60 million light years from Earth. NGC 2655 is a Seyfert galaxy. The galaxy has asymmetric dust lanes in the centre of the galaxy, tidal arms and extended neutral hydrogen gas and may have experienced recently a merger. The complex dynamics of the HI and optical tails suggest the galaxy may have undergonen more mergers in the past. a weak bar has been detected in infrared H band. The diametre of the disk of the galaxy is estimated to be 60 Kpc (195,000 ly).[2]
William Herschel discovered NGC 2655 in September 26, 1802 and descripted it as very bright and considerably large. The galaxy can be glimsed with a 4 inches telescope under dark skies nearly 10° from the north celestial pole.[3] One supernova has been observed in NGC 2655, SN 2011B,[4] a type Ia with peak magnitude 12.8.[5]
NGC 2655 is the brightest member of NGC 2655 group, which also contains the Sc galaxy NGC 2715, NGC 2591, and NGC 2748.[6][7] One of the gas structures of NGC 2655 is traling off toward the small galaxy UGC 4714.[2]
