Moving GroupIn astronomy, a moving group or moving cluster is a group of stars that have a common origin. They are no longer bound into a tight group such as (star clusters) a globular cluster or open cluster (galactic cluster), but instead have separated over time. They are primarily identified by their common movement vectors and ages. Identification by chemical composition is also used to factor in moving group memberships.
