HD 74272 is a star in the constellation Vela. It has the Bayer designation n Velorum, while HD 74272 is the identifier from the Henry Draper catalogue. This is a white hued star that is faintly visible to the naked eye with an apparent visual magnitude of 4.74.[1] It is located at a distance of approximately 1,800 light years from the Sun based on parallax.[2] The star is drifting further away with a radial velocity of +17 km/s.[1]

This is an aging, massive bright giant star with a stellar classification of A5 II.[3] It is an estimated 30 million years old with 8.8 times the mass of the Sun.[4] Having exhausted the supply of hydrogen at its core, it has expanded to around 33[2] times the radius of the Sun. The star is radiating 3,287[2] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 7,595 K.[2]
