The 22 pages that link to Open cluster, each with the reason it gives.

• Molecular cloudBroader topic: Some cloud regions produce groups of stars that remain associated after their gas disperses.

• Stellar parallaxRelated: Shared parallax measurements help determine cluster distances and membership.

• Color–magnitude diagramBroader topic: Its shared distance and origin make its plotted sequence comparatively easy to interpret.

• Messier catalogBroader topic: Open clusters such as the Pleiades and Beehive Cluster are among its best-known entries.

• Stellar associationCompared with: Unlike an association, an open cluster is gravitationally bound, at least initially.

• Spiral armBroader topic: Young clusters can reveal recent star formation within spiral structure.

• Star clusterBroader topic: Open clusters are the less densely packed major class of star cluster.

• Stellar ageBroader topic: A cluster’s shared age makes its turnoff point a powerful population-wide clock.

• Carina NebulaRelated: Young clusters in the Carina complex reveal where its stars formed together.

• GaiaRelated: Gaia’s distances and motions help identify cluster members and trace cluster evolution.

• PleiadesNarrower topic: The Pleiades is a nearby example of this kind of stellar group.

• Eagle NebulaRelated: The young cluster NGC 6611 supplies much of the radiation shaping the nebula.

• Galactic tideBroader topic: The Milky Way’s tidal field helps disperse open clusters over time.

• Omega CentauriCompared with: Its structure and typical age contrast with Omega Centauri’s dense, ancient stellar system.

• Messier objectBroader topic: Many Messier entries, including the Pleiades, are open clusters.

• SubgiantRelated: Cluster subgiants help locate the turnoff and estimate the cluster’s age.

• Rosette NebulaNarrower topic: NGC 2244 is an open cluster embedded in the Rosette’s central region.

• Double ClusterNarrower topic: NGC 869 and NGC 884 are separate open clusters that appear close together.

• Omega NebulaNarrower topic: The young cluster NGC 6618 is embedded in the nebula.

• Beehive ClusterNarrower topic: The Beehive is a nearby example of this kind of stellar grouping.

• Messier 7Narrower topic: Messier 7 is an example of this cluster type.

• Pi PuppisCompared with: Unlike a cluster, Pi Puppis denotes a specific multiple-star system.
