A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association. [1] Members of stellar associations and moving groups share similar kinematic properties, as well as similar ages and chemical composition. The list (below) is sorted by the distance to the Solar System.
In 1999, cluster RDCS J0849+4452 (RX J0849+4452, RXJ0848.9+4452) was found at z=1.261 [43] [46] In 1995 and 2001, the cluster around 3C 294 was announced, at z=1.786 [65] In 1992, observations of the field of cluster Cl 0939+4713 found what appears to be a background cluster near a quasar, also in the background. The quasar was measured at z=2. ...
This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud . There are over 1,000 known open clusters in the Milky Way galaxy, but the actual total may be up to ten times higher. [ 1 ]
Tr / Trumpler — Robert Julius Trumpler's open cluster list, published in Preliminary results on the distances, dimensions and space distribution of open star clusters; Tu — Tucker (double stars) Turner — David G. Turner (?) (open star clusters) (for example: Turner 9 at and near the variable star SU Cygni, aka 'SU Cygni cluster')
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies. List of NGC objects (1–1000) List of NGC objects (1001–2000) List of NGC objects (2001–3000)
The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
Pandora's Cluster: Sculptor: 00 h 14 m 19.5 s: −30° 23′ 19″ 3 III It seems to have formed from four different clusters involved in a series of collisions over a period of some 350 million years.
