Hadar

Hadar is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP 68702 (β Cen, HR 5267) in constellation Cen.

Etymology and History

From some ind-A name hadari (an untranslated proper name), for one of a pair of stars, the other one being al-wazn. Sci-A authors ventured to identify these stars as α/β Cen or α/β Col, but exactly what two stars were originally intended, and the significance of their names, is unknown. "Hadar" was arbitrarily applied to β Cen in recent times.
