HD 74772 (d Velorum) is a single star in the southern constellation of Vela. It is positioned near the Vela SNR, which gives it an intense X-ray background. The star is of apparent visual magnitude 4.05, and hence is visible to the naked eye. Based upon an annual parallax shift of , it is located 207 light years from the Sun. It is moving closer to the Earth with a heliocentric radial velocity of −2 km/s.
This is an evolved G-type giant star with a stellar classification of G6 III. The interferometry-measured angular diameter of this star is , which, at its estimated distance, equates to a physical radius of about 12 times the radius of the Sun. It has 3.2 times the mass of the Sun and is radiating 128 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 5,210 K.
