NGC 7726 is a large barred spiral galaxy located in the constellation Pegasus in the northern sky. It is estimated to be 348 million light-years from the Milky Way and about 150,000 light-years in diameter. Many other objects are located within a close proximity to NGC 7726, including NGC 7720, NGC 7728, IC 5341 and IC 5342. [2] [1] [3]
Messier 15 or M15 (also designated NGC 7078 and sometimes known as the Great Pegasus Cluster) is a globular cluster in the constellation Pegasus. It was discovered by Jean-Dominique Maraldi in 1746 and included in Charles Messier 's catalogue of comet -like objects in 1764.
1 Pegasi (1 Peg) is a triple star [10] system in the constellation Pegasus, located approximately 156 light years away from the Sun based on parallax. [1] It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.09. [2] The system is moving closer to the Earth with a heliocentric radial velocity of − ...
Eta Pegasi or η Pegasi, formally named Matar / ˈ m eɪ t ɑːr /, [11] [12] is a binary star in the constellation of Pegasus. The apparent visual magnitude of this star is +2.95, [2] making it the fifth-brightest member of Pegasus. Based upon parallax measurements, the distance to this star is about 214 light-years (66 parsecs) from the Sun. [1]
NGC 7777 is a lenticular galaxy [1] in the constellation of Pegasus. [2] It was discovered on 25 October 1876 by French astronomer Édouard Stephan. [3] See also.
51 Pegasi (abbreviated 51 Peg), formally named Helvetios / h ɛ l ˈ v iː ʃ i ə s /, [12] is a Sun-like star located 50.6 light-years (15.5 parsecs) from Earth in the constellation of Pegasus. It was the first main-sequence star found to have an exoplanet (designated 51 Pegasi b, officially named Dimidium) orbiting it. [13]
NGC 7769 is an unbarred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 3855 ± 25 km/s, which corresponds to a Hubble distance of 56.85 ± 4 Mpc (∼185 million light-years). [1] It was discovered by German-British astronomer William Herschel on 18 September 1784. [2]
