Webopen cluster, in astronomy, any group of young stars held together by mutual gravitation. See star cluster . This article was most recently revised and updated by Amy Tikkanen . Open clusters are very different from globular clusters. Unlike the spherically distributed globulars, they are confined to the galactic plane, and are almost always found within spiral arms. They are generally young objects, up to a few tens of millions of years old, with a few rare exceptions as old as a few billion years, such as Messier 67 (the closest and most observed old open cluster) for example. They form H II regions such as the Orion Nebula.
Web11 de ago. de 2003 · Star clusters are vital laboratories for testing theories of stellar dynamics and stellar evolution (e.g. Meylan & Heggie 1997 ).

The two types are …
An open cluster is a type of star cluster made of tens to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as they orbit the Galactic Center. This can result in a loss of clu…
