HIP 63242 and Its Planet

HIP 63242 is a star 510 light-years away with a spectral type of G8, placing it in the same temperature class as the Sun. Its reported mass estimate is 1.54 solar masses, larger than the Sun's, while its reported temperature of 4830 K is cooler than the Sun's. One planet has been found orbiting this star.

That planet, HIP 63242 b, was discovered in 2013 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HIP 63242 b has a minimum mass of 2920 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 9.18 times Jupiter's mass. It completes one orbit every 125 days.
