HD 68402 and Its Planet
HD 68402 is a star 256 light-years away with a spectral type of G5 IV/V. It has an age of 2 billion years, a mass of 1.12 solar masses, a radius of 1.02 solar radii, and a temperature of 5950 K. Its reported mass estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
HD 68402 b was discovered in 2016 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 976 Earth masses and an orbital period of 1100 days. Its minimum mass is larger than Earth's and roughly 3.07 times Jupiter's mass.
