List of nearby stellar associations and moving groups

From Wikipedia, the free encyclopedia

This list isincomplete; you can help byadding missing items.(February 2020)
Star density maps of the Gaia Catalogue of Nearby Stars.The Sun is located at the centre of both maps. The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups.

This is alist of nearby stellar associations and moving groups. Astellar association is a very loosestar cluster, looser than anopen cluster. Amoving group is the remnant of such a stellar association.[1] 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 theSolar System.

Nearby associations. Most of these are listed below.
