HD 140901 and Its Two Known Planets
HD 140901 is a G6IV star located 49.7 light-years from Earth. It is estimated to be 4.16 billion years old, with a mass of 0.99 solar masses and a radius of 0.95 solar radii. Its temperature is 5630 K, cooler than the Sun's. Two planets are known to orbit this host.
HD 140901 b was discovered in 2022 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 15.6 Earth masses, larger than Earth's, and its orbital period is 9.02 days, the shortest among the listed planets.
HD 140901 c was also discovered in 2022 by radial velocity. Its mass is 572 Earth masses, roughly 1.8 times Jupiter's mass and larger than Earth's. Its orbital period is 14400 days, the longest among the listed planets.
