Andromeda (constellation)}} is a {}-based template to be used at the bottom of articles about astronomical objects beyond the Solar System, located in the constellation of Andromeda. The template is divided into categories of stars , star clusters , nebulae , exoplanets , galaxies , galaxy clusters , and a miscellaneous "other" category.
a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
In Chinese astronomy, the stars that make up Andromeda were members of four different constellations that had astrological and mythological significance; a constellation related to Andromeda also exists in Hindu mythology. Andromeda is the location of the radiant for the Andromedids, a weak meteor shower that occurs in November.
Gamma Andromedae, Latinized from γ Andromedae, is the third-brightest point of light in the northern constellation of Andromeda. It is a multiple star system approximately 390 light-years from Earth. The system is drifting closer to the Sun with a radial velocity in the range of −12 to −14 km/s. [5]
Theta Andromedae is a binary star [11] system in the northern constellation of Andromeda. Theta Andromedae, Latinized from θ Andromedae, is its Bayer designation.It is located at a distance of approximately 173 light-years (53 parsecs) from the Sun, [1] and has an apparent visual magnitude of 4.6. [2]
9 Andromedae is the Flamsteed designation, while it bears the variable star designation AN Andromedae, or AN And. The maximum apparent visual magnitude of the system is 5.98, [3] which places it near the lower limit of visibility to the human eye.
10 Andromedae, abbreviated 10 And, is an astrometric binary [3] star system in the northern constellation of Andromeda. 10 Andromedae is the Flamsteed designation.It has an apparent visual magnitude of approximately 5.81, [2] which means it is faintly visible to the naked eye.
It was listed as entry number 34 in A Catalogue of Circumpolar Stars, published posthumously in 1838 by British astronomer Stephen Groombridge. [11] Based upon parallax measurements taken by the Gaia spacecraft, the system is located about 11.6 light-years (3.6 parsecs) from the Sun. This positions the pair among the nearest stars to the Solar ...
