Delta Ceti

Delta Ceti, Latinized from δ Ceti, is a single, blue-white hued star in the equatorial constellation of Cetus. The star's apparent visual magnitude of +4.06 means it is near to the cusp of the faintest third of the stars that are visible the ideally-placed naked eye. It is north of the celestial equator compared to the celestial north pole's . It is about WNW of the spiral galaxy M77 (but which at apparent magnitude 9.6 needs magnification to be made out and has an apparent size of by ). 
Distance and relative motion.
Based upon an annual parallax shift of as seen from Earth, it is around from the Sun. 
Motion relative to our system's trajectory includes a highly parting vector: with a net radial velocity of about . It moves minutely across the celestial sphere – yet just over four times more in right ascension than in declination. 
Inherent properties.
This is a Beta Cephei variable with a stellar classification of B2 IV. It varies in brightness with a period of 0.16114 days. The star is about 7−18 million years and has a low projected rotational velocity of around , suggesting it is either rotating slowly or is being viewed from nearly pole on. It has 8.4 times the mass of the Sun and 4.6 times the Sun's radius. The star is radiating around 4,000 times the Sun's luminosity from its photosphere at an effective temperature of roughly 
Name.
This star, along with α Cet (Menkar), λ Cet (Menkar), γ Cet (Kaffaljidhma), μ Cet, ξ1 Cet and ξ2 Cet were "Al Kaff al Jidhmah", "the Part of a Hand".
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.)
In Chinese, (), meaning "Circular Celestial Granary", refers to an asterism consisting of δ Ceti, α Ceti, κ1 Ceti, λ Ceti, μ Ceti, ξ1 Ceti, ξ2 Ceti, ν Ceti, γ Ceti, 75 Ceti, 70 Ceti, 63 Ceti and 66 Ceti. Consequently, the Chinese name for δ Ceti itself is (, .)
