HD 83183 is a single[9] star in the southern constellation of Carina. It has the Bayer designation h Carinae, while HD 83183 is the star's identifier from the Henry Draper catalogue. The star is blue-white in hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.08.[2] It is located at a distance of approximately 1,330 light years based on parallax,[1] and is drifting further away with a radial velocity of +18 km/s.[2] O. J. Eggen identified it as a member of the Pleiades group of co-moving stars.[10]
This object is a massive bright giant star with a stellar classification of B5 II.[3] It is 25[4] million years old and is spinning with a projected rotational velocity of 19 km/s.[7] The star has 9[4] times the mass of the Sun and about 18[5] times the Sun's radius. It is radiating 11,634 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 14,300 K.[6]
