A-type main sequence star in the constellation Cetus
Rho Ceti ,Latinized from ρ Ceti, is theBayer designation for astar in theequatorial constellation ofCetus . It is faintly visible to the naked eye with anapparent visual magnitude of 4.885.[ 2] parallax shift of 7.15 mas ,[ 1] light years .
This is anA-type main sequence star with astellar classification of A0 V.[ 3] projected rotational velocity of 219[ 8] oblate shape with anequatorial bulge that is 10% larger than the polar radius.[ 10] [ 6] radius of the Sun and is radiating 178 times thesolar luminosity from itsouter atmosphere at aneffective temperature of 8,905 K.[ 7]
This star, along withπ Cet ,ε Cet andσ Cet , was Al Sufi'sAl Sadr al Ḳaiṭos , the Whale's Breast[ 11]
According to the catalogue of stars in theTechnical Memorandum 33-507 - A Reduced Star Catalog Containing 537 Named Stars ,Al Sadr al Ḳaiṭos were the title for four stars :this star (ρ Cet) asAl Sadr al Ḳaiṭos I ,σ Cet asAl Sadr al Ḳaiṭos II ,ε Cet asAl Sadr al Ḳaiṭos III andπ Cet asAl Sadr al Ḳaiṭos IV [ 12]
