Alpha Capricorni (α Capricorni, abbreviated Alpha Cap, α Cap) is an optical double star in the constellation of Capricornus. The two physically unrelated components are designated:
They are separated by 0.11° on the sky, and resolvable with the naked eye, similar to Mizar and Alcor. α¹ Capricorni is fainter (apparent magnitude 4.27) than α² Capricorni (apparent magnitude 3.58).
Nomenclatureedit
α Capricorni (Latinised to Alpha Capricorni) is the system's Bayer designation; α1 and α2 Capricorni, those of the two components.
Alpha Capricorni bore the traditional names Algedi, Algiedi, Al Giedi or Giedi, derived from the Arabicالجديal-jady "the billy goat" or "kid". It also refers to the entire constellation of Capricornus. Giedi is sometimes also associated with Beta Capricorni. α1 and α2 Capricorni were also called Prima Giedi and Secunda Giedi, respectively. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[2] to catalogue and standardize proper names for stars. The WGSN approved the name Algedi for α2 Capricorni on 21 August 2016 and it is now so entered in the IAU Catalog of Star Names.[1]
