6 Ceti is a single[8]star in the equatorialconstellation ofCetus. It is visible to the naked eye with anapparent magnitude of 4.89.[2] The annualparallax shift as measured from Earth's orbit is 53.34 mas, which yields a distance estimate of 61.1 light years. The star is moving further from the Sun with a constantradial velocity of +16.70 km/s.[4] It is one of theIAU's standard velocity stars.[9]
Gray et al. (2006) assigned this star astellar classification ofF8 V Fe−0.8 CH−0.5,[3] indicating it is anF-type main-sequence star with an underabundance of iron and the CH molecule in itsstellar atmosphere. It is about 4.2 billion years old with 1.12[5] times themass of the Sun and is spinning with aprojected rotational velocity of 4.88 km/s.[6] The star is radiating 3.34[2] times theSun's luminosity from itsphotosphere at aneffective temperature of about 6,289 K.[5]
