HD 90853 is a single[ 9] star in thesouthern constellation Carina . It has theBayer designation s Carinae , whileHD 90853 is the identifier from theHenry Draper catalogue variable star with anapparent visual magnitude that ranges from 3.36 down to 3.51,[ 10] light-years from theSun based onparallax , and has anabsolute magnitude of −4.44.[ 2] radial velocity of +9 km/s.[ 2]
This is an agingbright giant orsupergiant star that has been assignedstellar classifications of F2II[ 3] [ 4] [ 5] mass of the Sun and has expanded to 45[ 6] Sun's radius . It is spinning with aprojected rotational velocity of 22 km/s.[ 7] [ 6] luminosity of the Sun from its enlargedphotosphere at aneffective temperature ofK [ 6]
