HD 94834 and Its Planet

HD 94834 is a K0 star 320 light-years away with one known planet. Its reported mass estimate is 1.11 solar masses and its reported radius estimate is 4.2 solar radii, both larger than the Sun's. Its reported temperature is 4800 K, cooler than the Sun's.

The planet, HD 94834 b, was discovered in 2018 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 94834 b has a minimum mass of 400 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 1.26 times Jupiter's mass. Its orbital period is 1580 days.
