Kappa Ceti (κ Cet / κ Cet) is the Bayer designation shared by two stars in the constellation of Cetus:

Kappa1 Ceti

Kappa¹ Ceti (κ¹ Cet, κ¹ Ceti) is a yellow dwarf star approximately 30 light-years away in the equatorial constellation of Cetus. The star was discovered to have a rapid rotation, roughly once every nine days. Though there are no extrasolar planets confirmed to be orbiting the star, Kappa¹ Ceti is considered a good candidate to contain terrestrial planets (like the Earth). The system is a candidate binary star, but has not been confirmed. The star should not be confused with the star Kappa² Ceti, which is ten times as distant.

Stellar components

Kappa¹ Ceti is a yellow dwarf star of the spectral type G5Ve. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. The star has roughly the same mass as the Sun, with 95% of the Sun's radius but only 85 percent of the luminosity. It is unclear whether the star is equal or is more enriched in elements heavier than hydrogen, but it is determined that the star has between 98 and 240 percent of the Sun's abundance of iron. Kappa¹ Ceti is much younger than the Sun, and may only be around 800 million years old.
