HD 148156 and Its Single Known Planet
HD 148156 is an F8 star located 186 light-years away, with one planet in orbit around it. The star's reported mass estimate is 1.22 solar masses, larger than the Sun's, and its reported radius estimate of 1.21 solar radii is also larger than the Sun's. Its temperature of 6310 K is hotter than the Sun's.
The planet HD 148156 b was discovered in 2009 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion, with repeated wobbles revealing the planet and its orbital period. HD 148156 b has a minimum mass of 270 Earth masses, a lower bound on its true mass that is larger than Earth's. Its orbital period is 1030 days.
