Cebalrai 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 86742 (β Oph, HR 6603) in constellation Oph.
Etymology and History
Applied in recent times from its ind-A name kalb al-ra'i, "the Shepherd's Dog" (in other traditions α Her and 28/29 Cep are given the same name). This dog, together with the shepherd (marked by α Oph), and the two lines of stars enclosing the Pasture, and all the dim stellar sheep in that portion of the sky (al-ghanam or al-aghnam for the sheep), seem to form a complete group of ind-A figures.
