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 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 ...
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.
The star is faintly visible to the naked eye, having an apparent visual magnitude of 5.68. [2] Based upon an annual parallax shift of 29.12 [ 1 ] mas as seen from Earth, it is located 112 light years away. 5 Andromedae is moving closer to the Sun with a radial velocity of −2.6 km/s. [ 2 ]
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 .
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.
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]
