HD 221246 or NGC 7686 1 is a star in open cluster NGC 7686, and it belongs to the northern constellation of Andromeda.With an apparent visual magnitude of 6.17, [2] it can be viewed by the naked eye only under very favourable conditions.
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 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]
HD 223229 is a suspected variable star in the northern constellation of Andromeda.It is a double star consisting of a magnitude 6.11 primary and a magnitude 8.73 companion. . The pair have an angular separation of 0.80″ along a position angle of 250°, as of 2009
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]
HD 895 is a multiple star system in the constellation Andromeda.Its apparent magnitude is 6.277, [2] so it can be seen by the naked eye under very favourable conditions. Based on parallax measured by Hipparcos, the system is located around 54 parsecs (180 ly) away, [4] and it is made of two different spectroscopic binary pairs.
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. Double star catalogues list two stars as optical companions.
HD 221776 is a double star in the northern constellation of Andromeda. With an apparent visual magnitude of 6.18, [ 2 ] it is viewable by the naked eye user very favourable conditions. The most luminous component has a spectral classification K5III, meaning that it is an orange giant star that has evolved off the main sequence .
