HD 142245 and Its Planet

HD 142245 is a K-type star 317 light-years away with one known planet. The star is estimated to be 2.3 billion years old. Its mass estimate is 1.69 solar masses, its radius estimate is 5.2 solar radii, and its temperature is 4880 K. The mass and radius estimates are larger than the Sun's, while the temperature is cooler than the Sun's.

The planet HD 142245 b was discovered in 2011 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its orbital period is 1300 days. Its minimum mass is 976 Earth masses, a lower bound on its true mass, roughly 3.07 times Jupiter's mass.
