Ancha

Ancha is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Latin. It is the name of HIP 110003 (θ Aqr, HR 8499) in constellation Aqr.

Etymology and History

A Latin word meaning "hip", used in the Medieval Latin Almagest in describing σ and ι/38 Aqr in the right and left hips, respectively (following an error, for Ptolemy had these stars in "the buttocks"). The word was applied as a star name to θ Aqr (correctly in Ptolemy's "right socket of the hip") in recent times.
