Errai

Errai 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 116727 (γ Cep, HR 8974) in constellation Cep.

Etymology and History

Applied in recent times from its ind-A name al-ra'i, "the Shepherd". This shepherd, with the sheep he attended (al-aghnam, marked by the various dim stars nearby), and the shepherd's dog (kalb al-ra'i,marked by 28/29 [ρ] Cep), seem to form a complete group of ind-A figures.
