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]
