HD 83183
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]
