HD 32963 and Its Planet

HD 32963 is a G5 star 124 light-years away, with a mass of 1.03 solar masses, a radius of 1.09 solar radii, and a temperature of 5740 K. Its reported radius estimate is larger than the Sun's. One planet orbits this host.

HD 32963 b was discovered in 2015 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. The planet's minimum mass is 222 Earth masses, larger than Earth's, and its orbital period is 2370 days. That minimum mass is a lower bound on its true mass, not an ordinary mass estimate.
