List of largest known star clusters Cluster name Diameter (light-years) Type of cluster Notes Terzan 7: 316 [1] Globular cluster: Messier 54: 306 [2] NGC 339: 238 [3] Messier 3: 226 [4] Messier 11 (Wild Duck Cluster) 190 [5] Open cluster: Messier 2: 174.4 [6] Globular cluster: Omega Centauri: 172 ± 12 [7] Largest globular cluster in the Milky ...
Globular cluster masses can be determined by observing the proper motion of nearby stars influenced by the cluster [1] [2] or by estimating the cluster's relaxation time. [ 3 ] Open clusters
Star clusters are large groups of stars held together by self-gravitation. Two main types of star clusters can be distinguished. Globular clusters are tight groups of ...
List of largest star clusters; List of most massive star clusters; List of stellar streams; M. Melotte catalogue; N. NGC 1847; NGC 1852; NGC 1860; NGC 1903; NGC 1943 ...
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 ]
A team of international astronomers recently announced the largest superstructure in the known universe. The immense structure named "Quipu" is estimated to stretch for an astonishing 1.4 billion ...
A red supergiant star orbited by a smaller B-type main-sequence star with a radius estimated between 13 [54] and 25 R ☉. [55] Widely recognised as being among the largest known stars. [ 21 ] Another estimate give a radius of 660 R ☉ [ 25 ] based on the Gaia DR3 distance of 1 kpc.
The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups. This is a list of nearby stellar associations and moving groups. 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 ...
