HD 2952 and Its Planet
HD 2952 is a K0 III star located 359 light-years away. Its reported mass estimate is 2.54 solar masses, its reported radius estimate is 12 solar radii, and its reported temperature is 4840 K, cooler than the Sun's. One planet orbits this host.
That planet, HD 2952 b, was discovered in 2013 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 285 Earth masses, larger than Earth's. A minimum mass is a lower bound on a planet's true mass. The planet's orbital period is 312 days.
