HD 139357 and Its Planet
HD 139357 is a K-type star 366 light-years away. Its spectral type, K4 III, indicates a cooler temperature class than the Sun. The star's reported mass estimate is 1.35 solar masses, larger than the Sun's, and its reported radius estimate is 11.5 solar radii, also larger than the Sun's. Its reported temperature is 4700 K, cooler than the Sun's, and its age is 3.07 billion years. One planet orbits this host.
That planet, HD 139357 b, was discovered in 2008 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 139357 b has a reported mass estimate of 6320 Earth masses, larger than Earth's and roughly 19.9 times Jupiter's mass. Its orbital period is 1120 days.
