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.[5] At that distance, the star has an apparent visual magnitude of 4.45,[2] 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.[11]

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.[3] 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.[6] The star has 1.44[6] times the mass of the Sun and 2.66 times the Sun's radius.[7] The abundance of iron, a measure of the star's metallicity, is a scant 38% of solar.[6] HD 60532 is radiating 9.3[7] times the luminosity of the Sun from its photosphere at an effective temperature of 6,095 K.[6]
