HD 134060 and Its Two Planets
HD 134060 is a G2V star 78.3 light-years away. A G-type dwarf like this is Sun-like, and this one is 5.6 billion years old. Its mass is 1.07 solar masses, its radius is 1.17 solar radii, and its temperature is 5910 K, so its reported mass and radius estimates are larger than the Sun's and its reported temperature is hotter. Two planets are known to orbit this star.
Both planets were discovered in 2019 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. HD 134060 b has a minimum mass of 10.1 Earth masses, larger than Earth's, and an orbital period of 3.27 days. HD 134060 c has a minimum mass of 29.3 Earth masses, also larger than Earth's, and an orbital period of 1290 days. Among the listed planets, HD 134060 b has the shortest year and the smallest minimum mass, while HD 134060 c has the longest year and the largest minimum mass.
