Encyclopedia
Gamma 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", the association of this star, along with α Cet
(Menkar), δ Cet
, λ Cet
(Menkar), μ Cet, ξ1 Cet and ξ2 Cet..
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
)
