HD 107148 and Its Two Known Planets
HD 107148 is a G-type main-sequence dwarf 161 light-years away, with a spectral type of G5 V. Its reported measurements include an age of 5 billion years, a mass of 1.1 solar masses, a radius of 1.17 solar radii, and a temperature of 5740 K; the radius estimate is larger than the Sun's. Two planets have been found orbiting this star.
HD 107148 b was discovered in 2005 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 66.7 Earth masses and an orbital period of 48.1 days, the longest year among the listed planets by reported estimates. HD 107148 c was discovered in 2021 by the same method. Its minimum mass is 19.9 Earth masses, smaller than b's and the smallest among the listed planets, and its orbital period is 18.3 days, the shortest year among the listed planets by reported estimates. Both planets' minimum masses are larger than Earth's.
