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.
The two stars orbit one another elliptically (e=0.44), [12] approaching as close as 4.2 AU and receding to 10.5 AU, with a period of just under twenty years. [ 6 ] HD 10307 A, the larger component, is a G-type main-sequence star similar to the Sun, only slightly brighter, hotter, larger, and older than the Sun—though with a slightly smaller mass.
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 ...
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.
66 Andromedae is a binary star [3] system in the northern constellation of Andromeda, near the northern border with Perseus. The designation is from the star catalogue of English astronomer John Flamsteed , first published in 1712.
Zeta Andromedae (Zeta And, ζ Andromedae, ζ And) is a star system in the constellation Andromeda. It is approximately 189 light-years from Earth. Zeta Andromedae is the star's Bayer designation. It also has the Flamsteed designation 34 Andromedae and multiple other designations in stellar catalogues.
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]
Omicron Andromedae is a multiple star containing at least three components. It may consist of two close pairs in a wider orbit, making a four-star system, [14] although the binarity of the primary star is in doubt. [11] This star system has a peculiar velocity of 34.5 ± 5.9 km/s. [14]
