HD 60532 is a star with two orbiting exoplanets in the southern constellation of Puppis. The designation HD 60532 takes its name from the Henry Draper Catalogue. The system is located at a distance of 85.5 light years from the Sun, and is drifting further away with a radial velocity of 61 km/s. At that distance, the star has an apparent visual magnitude of 4.45, which is bright enough to be faintly visible to the naked eye. The motion of this system through space brought it within 10.3 light-years of the Sun some 408,600 years ago.
The spectrum of this star shows blended features of an F-type main-sequence star and an evolving subgiant star, with a corresponding stellar classification of F6 IV-V. It is an estimated 2.7 billion years old with a projected rotational velocity of 8 km/s and a low level of magnetic activity in its chromosphere. The star has 1.44 times the mass of the Sun and 2.66 times the Sun's radius. The abundance of iron, a measure of the star's metallicity, is a scant 38% of solar. HD 60532 is radiating 9.3 times the luminosity of the Sun from its photosphere at an effective temperature of 6,095 K.
