HR 3159 is a single [10] star in the southern constellation of Carina, positioned near the southern constellation border with Volans. It has the Bayer designation D Carinae; HR 3159 is the Bright Star Catalogue designation. This object has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of +4.81. [2] It is located at a distance of approximately 499  light years from the Sun based on parallax, [1] and is drifting further away with a radial velocity of 22 km/s.

This object is a B-type main-sequence star with a stellar classification of B4V, [3] which indicates it is undergoing core hydrogen fusion. The star has a radius of nearly four times the radius of the Sun, [5] and over six [4] times the Sun's mass. Age estimates range from 17 [4] up to 176 [8]  million years old, and it is spinning with a projected rotational velocity of 43 km/s. [6] It is radiating 912 [6] times the luminosity of the Sun from its photosphere at an effective temperature of 16,983 K. [6]
