Gamma Ceti

Gamma Ceti (γ Cet, γ Ceti) is a star in the constellation Cetus. It has the traditional name Kaffaljidhma. The title Kaffaljidhma was derived from Arabic الكف الجذماء Al Kaff al Jidhmah, "The cut-short hand"[1], the association of this star, along with α Cet (Menkar), δ Cet, λ Cet (Menkar), μ Cet, ξ1 Cet and ξ2 Cet.[2].

According to the catalogue of stars in the Technical Memorandum 33-507 - A Reduced Star Catalog Containing 537 Named Stars, Al Kaff al Jidhmah were the title for five stars :γ Cet as Kaffaljidhma, ξ1 Cet as Al Kaff al Jidhmah I, ξ2 Cet as Al Kaff al Jidhmah II, δ Cet as Al Kaff al Jidhmah III and μ Cet as Al Kaff al Jidhmah IV (exclude α Cet and λ Cet)[3]

In Chinese, 天囷 (Tiān Qūn), meaning Circular Celestial Granary, refers to an asterism consisting of γ Ceti, α Ceti, κ1 Ceti, λ Ceti, μ Ceti, ξ1 Ceti, ξ2 Ceti, ν Ceti, δ Ceti, 75 Ceti, 70 Ceti, 63 Ceti and 66 Ceti.[4] Consequently, γ Ceti itself is known as 天囷八 (Tiān Qūn bā, English: the Eighth Star of Circular Celestial Granary.)[5]
