NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784. [ 4] NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC ...
HCG 92, Arp 319, VV 288, [1] SQ [2] Stephan's Quintet is a visual grouping of five galaxies of which four form the first compact galaxy group ever discovered. [2] The group, visible in the constellation Pegasus, was discovered by Édouard Stephan in 1877 at the Marseille Observatory. [3] The group is the most studied of all the compact galaxy ...
List of nearest galaxies. This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups, the M81 Group and the Centaurus A ...
The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC ( New General Catalogue) 598 . With the D 25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years ), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies ...
NGC 7331 is a spiral galaxy located in Pegasus, 38 million light-years distant with a redshift of 0.0027. It was discovered by musician-astronomer William Herschel in 1784 and was later one of the first nebulous objects to be described as "spiral" by William Parsons. Another of Pegasus's galaxies is NGC 7742, a Type 2 Seyfert galaxy.
The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each ...
Pegasus Galaxy, or Pegasus Dwarf Galaxy, or Pegasus Dwarf, can mean several things: Pegasus Dwarf Irregular Galaxy or Peg DIG, a member of the Local Group of galaxies. Pegasus Dwarf Spheroidal Galaxy or Pegasus II, a member of the Local Group of galaxies, a satellite of the Andromeda Galaxy. Pegasus Galaxy ( Stargate), a location in the science ...
Characteristics. Type. E2 [1] Other designations. UGC 12523, MCG +01-59-052, PGC 71121 [1] NGC 7619 is an elliptical galaxy located in the constellation Pegasus. [2] NGC 7619 and NGC 7626 [3] are the dominant and brightest members of the Pegasus galaxy cluster. [4] Both of them were discovered by William Herschel on September 26, 1785.
