HD 10975 and Its Single Known Planet

HD 10975 is a K0 III star located 380 light-years away. Its reported mass estimate is 1.41 solar masses, larger than the Sun's, and its reported radius estimate is 11.2 solar radii, also larger than the Sun's. The star's reported temperature of 4840 K is cooler than the Sun's. One planet orbits this host.

That planet, HD 10975 b, was discovered in 2021 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 10975 b has a minimum mass of 143 Earth masses, a lower bound on its true mass that is larger than Earth's, and an orbital period of 284 days.
