List of nearby stellar associations and moving groups

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 is sorted after the distance to the solar system.
