HD 238914 and Its Planet

HD 238914 is a K7 star 1690 light-years away, with a mass of 1.47 solar masses, a radius of 12.7 solar radii, and a temperature of 4770 K. Its reported radius is larger than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this star.

That planet, HD 238914 b, was discovered in 2018 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. Its minimum mass, a lower bound on its true mass, is 1910 Earth masses, roughly 6 times Jupiter's mass and larger than Earth's. It completes one orbit in 4100 days.
