This article is about s Carinae. For S Carinae, see
HD 88366 .
HD 90853 is a single[ 9] star in the southern constellation Carina . It has the Bayer designation s Carinae , while HD 90853 is the identifier from the Henry Draper catalogue variable star with an apparent visual magnitude that ranges from 3.36 down to 3.51,[ 10] light-years from the Sun based on parallax , and has an absolute magnitude of −4.44.[ 2] radial velocity of +9 km/s.[ 2]
This is an aging bright giant or supergiant star that has been assigned stellar classifications of F2II[ 3] [ 4] [ 5] mass of the Sun and has expanded to 45[ 6] Sun's radius . It is spinning with a projected rotational velocity of 22 km/s.[ 7] [ 6] luminosity of the Sun from its enlarged photosphere at an effective temperature of K [ 6]
