HD 27631 and Its Planet
HD 27631 is a G3 IV-V star 164 light-years away, with an age of 4.4 billion years, a mass of 0.94 solar masses, a radius of 1 solar radii, and a temperature of 5740 K. Its reported mass estimate is smaller than the Sun's. One planet is known to orbit this host.
HD 27631 b was discovered in 2012 by radial velocity, the method that measures the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 475 Earth masses and an orbital period of 2200 days. That minimum mass is larger than Earth's and roughly 1.49 times Jupiter's mass.
