NGC 2550A is aspiral galaxy in theconstellation ofCamelopardalis. Its velocity with respect to thecosmic microwave background is 3670 ± 10 km/s, which corresponds to aHubble distance of 176.5 ± 12.4 Mly (54.12 ± 3.79 Mpc).[1] The discovery of this galaxy is credited toPhilip C. Keenan, in his paperStudies of Extra-Galactic Nebulae. Part I: Determination of Magnitudes, published inThe Astrophysical Journal in 1935.[2]
According to A.M. Garcia, NGC 2550A is a member of theNGC 2523galaxy group (also known asLGG 154).[3] This group contains five galaxies, includingNGC 2441, NGC 2523,UGC 4041, and UGC 4199.
