  skos:definition "En astronomie, un amas ouvert est un amas stellaire groupant environ de 100 à 10 000 étoiles de même âge liées entre elles par la gravitation, et dont le diamètre varie de 1,5 à 15 pc, avec une moyenne de 4 à 5 pc. Les amas ouverts sont peu lumineux et s’observent essentiellement dans notre Galaxie, où ils se situent dans le plan galactique, et dans les galaxies proches : les deux Nuages de Magellan et la galaxie d’Andromède. (Wikipedia, L'Encylopédie Libre, <a href=\"https://fr.wikipedia.org/wiki/Amas_ouvert\" target=\"_blank\">https://fr.wikipedia.org/wiki/Amas_ouvert</a>)"@fr, " 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.
