data |
HD 60532 is a white (F-type) main sequence star located approximately 84 light-years away in the constellation of Puppis, taking its primary name from its Henry Draper Catalogue designation. It is calculated to be 1.44 times more massive than the Sun. The star is only 59% as old as our Sun (2.7 Gyr) and has metallicity of only 38% that of our Sun. In 2008, two extrasolar planets were discovered in orbit around it.
Planetary system
In September 2008, two Jupiter-like planets were found orbiting the star.[5] The orbital periods of these two planets appear to be in 3:1 resonance.[9]
