HD 108202 and Its Planet

HD 108202 is a K4/5 V star located 126 light-years away. Its spectral type marks it as a main-sequence dwarf, and its reported mass estimate is 0.72 solar masses, smaller than the Sun's. The star's reported radius estimate is 0.664 solar radii, also smaller than the Sun's, and its temperature is 4560 K, cooler than the Sun's. One planet is known to orbit this host.

That planet, HD 108202 b, was discovered in 2023 by 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 108202 b has a reported mass estimate of 953 Earth masses, larger than Earth's and roughly 3 times Jupiter's mass. Its orbital period is 2990 days.
