Names For This Star

The name Bellatrix is Latin, meaning " The Female Warrior". Therefore this star is sometimes known as "The Amazon Star".

According to Allen, the first usage of the name "Bellatrix" for this star was in the Alfonsine Tables published in Spain in 1252 under the patronage of King Alfonso X of Leon and Castile. This name represents a very free translation of the Arabic name for this star, Al Najid meaning "The Conqueror".
