Global InformationList of nearby stellar associations and moving groups information
 | This list is incomplete; you can help by adding missing items. (February 2020) |
This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association. Members of stellar associations and moving groups share similar kinematic properties, as well as similar ages and chemical composition.
The list (below) is sorted by the distance to the Solar System.
