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).

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]
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.
