HD 61248 is a single[7] star in the southern constellation of Carina. It has the Bayer designation Q Carinae,[8] while HD 61248 is the star's identifier in the Henry Draper Catalogue. This star has an orange hue and is visible to the naked eye with an apparent visual magnitude of 4.93.[2] Based upon parallax measurements, it is located approximately 402 light years in distance from the Sun. The object is drifting further away with a radial velocity of +63 km/s,[1] having come to within Script error: No such module "convert". some 1.8 million years ago.[2]
This is an aging giant star with a stellar classification of K3 III,[3] which means it is no longer undergoing core hydrogen fusion. It has expanded to 30 times the Sun's radius and is radiating 279 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,289 K.[1]
