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]
NGC 85 is an interacting spiral or lenticular galaxy estimated to be about 200 million light-years away in the constellation of Andromeda. It was discovered by Ralph Copeland in 1873 and its apparent magnitude is 15.7. [4] The galaxy appears to be interacting with the companion spiral IC 1546.
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]
UGC 1840, also known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the Solar System in the Andromeda constellation. [2] The earliest known reference to the pair of galaxies is in part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +07-06-002.
mcg +07-06-015, pgc 9222 [2] NGC 912 is a compact lenticular galaxy located in the constellation Andromeda about 197 million light years from the Milky Way . It was discovered by French astronomer Édouard Stephan in 1878.
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 169 is an unbarred spiral galaxy located in the constellation Andromeda. It was discovered on September 18, 1857, by R. J. Mitchell. [2] NGC 169 has a smaller companion named NGC 169A, also designated IC1559. The two are currently interacting, and the pair is included in Halton Arp's Atlas of Peculiar Galaxies. [3]
