Epsilon Ceti, Latinized from ε Ceti, is the Bayer designation for a binary star system located in the equatorial constellation of Cetus. It is faintly visible to the naked eye with an apparent visual magnitude of +4.84. Based upon an annual parallax shift of 14.58 mas, it is located around 98 light-years away from the Sun.

  • Epsilon Ceti, Latinized from ε Ceti, is the Bayer designation for a binary star system located in the equatorial constellation of Cetus. It is faintly visible to the naked eye with an apparent visual magnitude of +4.84. Based upon an annual parallax shift of 14.58 mas, it is located around 98 light-years away from the Sun. This is a line-width spectroscopic binary star system. It has an orbital period of 2.65 years and an eccentricity of 0.23. The semimajor axis is 0.11 AU, or 11% of the distance between the Sun and the Earth, and the orbital plane is inclined at an angle of 24.2°.The primary member, component A, is an F-type main-sequence star with a stellar classification of F2 V. The spectrum of the secondary, component B, can not be readily separated from that of the primary, so its type can only be estimated as a main-sequence star lying in the range between F7 V and G4 V. The system is estimated to be 1.8 billion years old, with the primary having 1.4 times the mass of the Sun and the secondary being about equal to the Sun's mass. (en)

  • Epsilon Ceti (ε Ceti, förkortat Epsilon Cet, ε Cet) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den östra delen av stjärnbilden Valfisken (stjärnbild).

Baserat på parallaxmätning inom Hipparcosuppdraget på ca 35,1 mas, beräknas den befinna sig på ett avstånd av ca 93 ljusår (ca 29 parsek) från solen. (sv)
