Since the time of Ptolemy, Andromeda has remained a constellation and is officially recognized by the International Astronomical Union. Like all those that date back to a pattern known to Ptolemy, it is attributed to a wider zone and thus many surrounding stars. [17] [18] In 1922, the IAU defined its recommended three-letter abbreviation, "And ...
NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. [3] The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster.

NGC 752 (also known as Caldwell 28) is an open cluster in the constellation Andromeda.The cluster was discovered by Caroline Herschel in 1783 and cataloged by her brother William Herschel in 1786, although an object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654.
Xi Andromedae (ξ Andromedae, abbreviated Xi And, ξ And), officially named Adhil / ə ˈ d ɪ l /, [7] [8] is a solitary [3] star in the northern constellation of Andromeda. It has an apparent magnitude of +4.9. [2] Based on parallax measurements obtained during the Gaia mission, it lies at a distance of roughly 223 light-years (68 parsecs ...
Gamma Andromedae, Latinized from γ Andromedae, is the third-brightest point of light in the northern constellation of Andromeda. It is a multiple star system approximately 390 light-years from Earth. The system is drifting closer to the Sun with a radial velocity in the range of −12 to −14 km/s. [5]
