NGC 2655 is a lenticular galaxy in the northern constellation of Camelopardalis.[1] It is at a distance of 60 million light years from Earth. NGC 2655 is a Seyfert galaxy.[2] The galaxy has asymmetric dust lanes in the centre of the galaxy, tidal arms and extended neutral hydrogen gas and may have recently experienced a merger. The complex dynamics of the HI and optical tails suggest the galaxy may have undergone more mergers in the past. A weak bar has been detected in infrared H band. The diameter of the disk of the galaxy is estimated to be 60 Kpc (195,000 ly).[3]

William Herschel discovered NGC 2655 in September 26, 1802 and described it as very bright and considerably large. The galaxy can be glimpsed with a 4-inch telescope under dark skies nearly 10° from the north celestial pole.[4]

NGC 2655 is the brightest member of the NGC 2655 group, which also contains the Sc galaxy NGC 2715, NGC 2591, and NGC 2748.[5][6] One of the gas structures of NGC 2655 is trailing off toward the small galaxy UGC 4714.[3]

Supernova

One supernova has been observed in NGC 2655.
