[2] 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.

[3] One supernova has been observed in NGC 2655, SN 2011B,[4] a type Ia with peak magnitude 12.8.

[6][7] One of the gas structures of NGC 2655 is trailing off toward the small galaxy UGC 4714.
