open cluster
Définition(s)
- An open cluster is a loose aggregation of dozens or hundreds of young stars, in a volume of space typically less than 50 light-years across. Open clusters are only weakly held together by gravity and are fated to disperse over a period, typically, of several hundred million years. Some much older open clusters are known, however. For example, M67 in Cancer, which lies about 2,800 light-years away, is at least 4 billion years old but is located well away from the galactic plane and as a result is less liable to disruption.
