HD 7199 and Its Planet
HD 7199 is a K0 IV/V star located 118 light-years away. It has one known planet. The star is estimated to be 6.79 billion years old, with a mass of 0.89 solar masses, a radius of 0.96 solar radii, and a temperature of 5390 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet HD 7199 b was discovered in 2011 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 7199 b has a minimum mass of 85.8 Earth masses and an orbital period of 615 days. Its minimum mass is larger than Earth's.
