Open star clusters


Stars may form by the dozens or hundres in groups that maintain their identity at least through the early ages of their stars’ lives, perhaps much longer. The result we see is galactic star clusters, more commonly known as open star clusters, because their density o stars is less and their tenacity for staying together is weaker than the other major kind of star cluster, such as globular clusters.

Some examples about open star clusters are; NGC 752, the double star cluster (NGC 869 and NGC 884), M34, alpha persei cluster, the pleiades (M45), NGC 1502, the hyades, collinder 464, M38, M36, M37, M35, NGC 21258, NGC 2232, NGC 2244, NGC 2264, M41, M50, M47, M46, M47, M93, NGC 2451, NGC 2477, NGC 2516, NGC 2547, M48, M44, M67, NGC 3532, NGC 3766, the coma star cluster, the kappa crucis star cluster, NGC 6025, NGC 6193, NGC 6231, M6, M7, IC 4665, M23, M21, NGC 6530, M24, M16, NGC 6633, M25, M11, the coathanger (brocchi’s cluster), M39 and M52.
