N Carinae is a single[9] star in the constellation Carina, just to the northeast of the prominent star Canopus. This object has a white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.35.[2] Based on parallax, it is located at a distance of approximately 1,360 light years from the Sun.[1] It has an absolute magnitude of −3.75,[2] and is drifting further away with a radial velocity of +22.5 km/s.[2]
This object has a stellar classification of A0II,[3] matching a massive bright giant. In the past it had received a class of B9III,[4] which is sometimes still used.[5] The star is 37 million years old with 7.9 times the mass of the Sun.[5] It is spinning with a projected rotational velocity of 47 km/s.[7] N Carinae is radiating 3,411[2] times the luminosity of the Sun from its photosphere at an effective temperature of 8,004 K.[6]
