The Coma Cluster (Abell 1656) is a large cluster of galaxies that contains over 1,000 identified galaxies. [ 2 ] [ 3 ] Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster . [ 8 ]
The Coma Supercluster (SCl 117) is a nearby supercluster of galaxies that includes the Coma Cluster (Abell 1656) and the Leo Cluster (Abell 1367). Located 300 million light-years from Earth in the constellation Coma Berenices , [ 2 ] it is in the center of the Great Wall and a part of the Coma Filament . [ 3 ]
The Coma Star Cluster (also known as Melotte 111 or Collinder 256) is a nearby open cluster located in the constellation Coma Berenices. The cluster contains about 40 brighter stars (between magnitudes 5 and 10) with a common proper motion. The brighter stars of the cluster make out a distinctive "V" shape as seen when Coma Berenices is rising.
Dragonfly 44 is an ultra diffuse galaxy in the Coma Cluster. [1] [3] [2] [4] This galaxy is well-known because observations of the velocity dispersion in 2016 suggested a mass of about one trillion solar masses, about the same as the Milky Way.
IC 4051 is a large elliptical galaxy [8] in the northern constellation of Coma Berenices. It was discovered by the French astronomer Guillaume Bigourdan on April 12, 1891. [9] This object is located 14′ east of the core of the large Coma Cluster of galaxies, [5] [10] at a distance of 330 million light-years (100 Mpc) from the Milky Way. [4]
The Coma Cluster is located at exactly the center of the Coma Supercluster, which is one of the nearest superclusters to the Laniakea Supercluster. The Coma Supercluster itself is within the CfA Homunculus, the center of the CfA2 Great Wall, the nearest galaxy filament to Earth and one of the largest structures in the known universe.
NGC 5053 is the New General Catalogue designation for a globular cluster in the northern constellation of Coma Berenices.It was discovered by German-British astronomer William Herschel on March 14, 1784 and cataloged as VI-7.
NGC 4147 is the New General Catalogue identifier for a globular cluster of stars in the northern constellation of Coma Berenices.It was discovered by English astronomer William Herschel on March 14, 1784, who described it as "very bright, pretty large, gradually brighter in the middle". [8]
