Caph

Caph 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 746 (β Cas, HR 21) in constellation Cas.

Etymology and History

Applied in recent times from an abbreviation of its ind-A name al-kaff al-khadib "the Stained Hand", alternatively and more correctly used for all the brighter stars of today's Cassiopeia (probably α, β, γ, δ, and ε). The ind-A figure here represented a hand with its finger-tips stained reddish-brown in the traditional Eastern way using henna leaves. al-kaff al-khatdib, in turn, was part of the larger ind-A asterism kaff althurayya al-yumna al-mabsuta, "the Outstretched Right Hand of the Pleiades". The latter extended from today's Taurus through Perseus into Cassiopeia. A second hand (the Pleiades were a "head" from which two arms or hands radiated) was al-kaff al-jadhma', "the Amputated Hand", in today's Cetus.
