HD 218566 and Its Planet
HD 218566 is a K3V star 94 light-years away. Its mass is 0.88 solar masses, its radius is 0.79 solar radii, and its temperature is 4930 K. It is 8.5 billion years old. These stellar measurements describe the star itself, and its reported mass estimate, radius estimate, and temperature are each smaller or cooler than the Sun's. One planet is known to orbit this host.
That planet, HD 218566 b, was discovered in 2010 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. Its minimum mass is 63.6 Earth masses, larger than Earth's, and its orbital period is 226 days.
