NGC 708 is an elliptical galaxy located 240 million light-years away [2] in the constellation Andromeda and was discovered by astronomer William Herschel on September 21, 1786. [3] It is classified as a cD galaxy [ 4 ] [ 5 ] and is the brightest member of Abell 262 .
NGC 561 is a barred spiral galaxy located in the constellation Andromeda. [3] Its speed relative to the cosmic microwave background is 4,395 ± 20 km/s, which corresponds to a Hubble distance of 64.8 ± 4.6 Mpc (~211 million ly). [4] NGC 561 was discovered by Prussian astronomer Heinrich d'Arrest in 1862. [5]
2 Andromedae, abbreviated 2 And, is a binary star [4] system in the northern constellation of Andromeda. 2 Andromedae is the Flamsteed designation . It is a faint star system but visible to the naked eye with a combined apparent visual magnitude of 5.09. [ 3 ]
NGC 7686 is a moderately-sized open cluster in the constellation Andromeda, containing about 80 stars. [2] At magnitude 5.6, it is an easy target for binoculars and small telescopes. [3] According to Johnson et al. (1961), the "color-magnitude diagram shows merely a uniform scatter with no significant tendency to show a cluster main sequence ...
NGC 317 is a pair of interacting galaxies, consisting of a lenticular galaxy NGC 317A (also designated as PGC 3442) and a spiral galaxy NGC 317B (also designated as PGC 3445), in the constellation Andromeda. It was discovered on October 1, 1885 by Lewis Swift. [2]
NGC 7662 is a planetary nebula located in the northern constellation Andromeda.It is known as the Blue Snowball Nebula, Snowball Nebula, and Caldwell 22.This nebula was discovered October 6, 1784 by the German-born English astronomer William Herschel.
HD 16028 is a star in the constellation Andromeda.Its apparent magnitude is 5.71. [2] Located approximately 225 parsecs (730 ly) distant, [1] it is an orange giant of spectral type K3III, [3] a star that has used up its core hydrogen and has expanded.
Map showing the location of NGC 752. 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.
