"Cluster" redirects here. For galaxy clusters, see Galaxy cluster.

Star clusters are massive groups of stars inside galaxies. There are two classes of star clusters: globular clusters are very large, dense clusters containing between a few hundred and a million stars and measuring a few hundred light years across, and open clusters, are smaller groups, usually containing a few score stars, and measuring no more than a hundred light-years across. Open clusters also have a subtype known as moving groups which are clusters which move through the galaxy along with their constituent stars.
