NGC 2552 is a Magellanic spiral galaxy located some 22[2] million light years away. It can be found in constellation of Lynx. This is a type of unbarred dwarf galaxy, usually with a single spiral arm. It is inclined by 41° to the line of sight from the Earth along a position angle of 229°.[2] The measured velocity dispersion of the stars in NGC 2552 is relatively low—a mere 19 ± 2 km/s.[3] This galaxy forms part of a loose triplet that includes NGC 2541 and NGC 2500, which together belong to the NGC 2841 group.[4]
