Al Minliar al Ghurab (Arabic ألمنخر ألغرب al-manxar al-ghurab) or Minkar al Ghyrab appeared in the catalogue of stars in the Calendarium of Al Achsasi al Mouakket, which was translated into Latin as Rostrum Corvi (beak of the crow).
In Chinese astronomy, Alchiba is called 右轄, Pinyin: Yòuxiá, meaning Right Linchpin, because it stands alone in the Right Linchpin asterism, Chariot mansion (see: Chinese constellation), 右轄 (Yòuxiá), westernized into Yew Hea by R.H. Allen.
Alchiba belongs to the spectral class F0 and has apparent magnitude +4.00. It is 48 light years from Earth. This star is suspected of being a spectroscopic binary, although this has not yet been confirmed.
USS Alchiba (AKA-6) is a former United States Navy ship.
