6 Ceti

6 Ceti is a single^[8] star in the equatorial constellation of Cetus. It is visible to the naked eye with an apparent magnitude of 4.89.^[2] The annual parallax 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 constant radial velocity of +16.70 km/s.^[4] It is one of the IAU's standard velocity stars.^[9]

Gray et al. (2006) assigned this star a stellar classification of F8 V Fe−0.8 CH−0.5,^[3] indicating it is an F-type main-sequence star with an underabundance of iron and the CH molecule in its stellar atmosphere. It is about 4.2 billion years old with 1.12^[5] times the mass of the Sun and is spinning with a projected rotational velocity of 4.88 km/s.^[6] The star is radiating 3.34^[2] times the Sun's luminosity from its photosphere at an effective temperature of about 6,289 K.^[5]
