Rho Ceti , Latinized from ρ Ceti, is the Bayer designation for a star in the equatorial constellation of Cetus. It is faintly visible to the naked eye with an apparent visual magnitude of 4.885.[2] The distance to this star, based upon an annual parallax shift of 7.15 mas,[1] is around 460 light years.
This is an A-type main sequence star with a stellar classification of A0 V.[3] It is spinning rapidly with a projected rotational velocity of 219[8] km/s, giving the star an oblate shape with an equatorial bulge that is 10% larger than the polar radius.[10] The star has an estimated size 3.1[6] times the radius of the Sun and is radiating 178 times the solar luminosity from its outer atmosphere at an effective temperature of 8,905 K.[7]
