List of nearby stellar associations and moving groups

January 09, 2023

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.

Nearby stellar associations and moving groups. The green cross in the middle shows the position of the Sun.
Close up on the Orion Arm, with major stellar associations (yellow), nebulae (red) and dark nebulae (grey) around the Local Bubble.
Main associations of the galactic plane in the night sky

The list is sorted by the distance to the Solar System.
