HD 212301 and Its Planet

HD 212301 is a star 177 light-years away with one known planet. The host is an F8 star with a reported mass of 1.25 solar masses and a radius of 1.1 solar radii, both larger than the Sun's. Its temperature is 6300 K, hotter than the Sun's, and its age is given as a reported upper limit of 1 billion years.

The planet HD 212301 b was discovered in 2005 by the radial velocity method, which tracks the wobble a planet's gravity induces in its star's motion. Its minimum mass is 162 Earth masses, larger than Earth's, and its orbital period is 2.25 days.
