HD 79447 is a single[8] star in the southern constellation of Carina. It has the Bayer designation i Carinae, while HD 79447 is the identifier from the Henry Draper catalogue. This star has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of +3.96.[1] It is located at a distance of approximately 540 light years from the Sun based on parallax,[2] and has an absolute magnitude of −2.14.[1] The star drifted further away with a radial velocity of +18 km/s.[1] It is a candidate member of the Lower Centaurus–Crux group of the Sco OB2 association.[9]
This object is a B-type main-sequence star with a stellar classification of B3V.[3] A surface magnetic field has been detected with a strength on the order of Script error: No such module "val"..[9] It has an estimated age of around 39[4] million years with no measured spin rate.[6] The star has about 5.6[5] times the radius of the Sun and 7[4] times the Sun's mass. It is radiating over two thousand[1] times the luminosity of the Sun from its photosphere at an effective temperature of 18,900 K.[3]
