History of the star: The Arabic name for this star marking the body of Grus, the Crane, is Alnair is An-Nayyir (1), "The bright one", (i.e. of the Fish's Tail), an obvious reference to its former association with Piscis Austrinus in Arabic astronomy.

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889]. 

The astrological influences of the constellation: A retiring, active, proud, watchful, kind, idealistic and devoted nature, with a liking for astronomy. (Fixed Stars and Constellations in Astrology , Vivian E. Robson, 1923)
