HD 204941 and Its Planet
HD 204941 is a K1/2 V star located 93.7 light-years away. This spectral type indicates a main-sequence star somewhat cooler than the Sun. The star is estimated to be 6.67 billion years old, with a mass of 0.74 solar masses, a radius of 0.72 solar radii, and a temperature of 5060 K. Compared with the Sun, its reported mass and radius estimates are smaller, and its reported temperature is cooler. One planet has been identified orbiting this host.
HD 204941 b was discovered in 2011 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 73.1 Earth masses, a lower bound on its true mass that is larger than Earth's. Its orbital period is 1730 days.
