HD 30479 (HR 1531) is a solitary star in the southern circumpolar constellation Mensa. It has an apparent magnitude of 6.04,[1] making it barely visible to the naked eye even under ideal conditions. It is located at a distance of 540 light years[2] but is receding with a heliocentric radial velocity of Template:Val.[3]

HD 30479 has a stellar classification of K2 III,[4] indicating that it is an early K-type giant star and has an angular diameter of Template:Val[5] (after limb darkening correction). This yields a radius 17.99[6] times that of the Sun at its estimated distance. At present it has 1.28[7] times the mass of the Sun and radiates at 116[8] times the luminosity of the Sun at an effective temperature of 4,390[5] K from its enlarged photosphere, which gives it an orange glow. HD 30479 is believed to be one of the metal-deficient members of the young disk population[9] with an iron abundance of 71%[9] that of the Sun. Currently, it spins leisurely with a projected rotational velocity less than Template:Val,[10] common for giants.
