HD 143105 b: A Lone Planet Around a Hotter, Heavier Star

HD 143105 is a single star located 153 light-years away, and one planet orbits it. The host is an F5 star with a reported mass of 1.51 solar masses and a temperature of 6380 K. Its mass estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

The system's only known planet, HD 143105 b, was found in 2016 using the radial velocity method, which tracks the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 385 Earth masses and an orbital period of 2.2 days. Its minimum mass is larger than Earth's and is roughly 1.21 times Jupiter's mass.
