HD 90853 is a single [9] star in the southern constellation Carina. It has the Bayer designation s Carinae, while HD 98053 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 6,598  K . [6]
