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. This is a variable star with an apparent visual magnitude that ranges from 3.36 down to 3.51,[10] and thus is bright enough to be visible to the naked eye. It is located at a distance of approximately 1,340 light-years from the Sun based on parallax, and has an absolute magnitude of −4.44.[2] The star is drifting further away with a 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] and F0Ib,[4] respectively. It has seven[5] times the mass of the Sun and has expanded to 45[6] times the Sun's radius. It is spinning with a projected rotational velocity of 22 km/s.[7] The star is radiating 3,466[6] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of Script error: No such module "val"..[6]
