6 Lyn and Its Planet
6 Lyn is a star 178 light-years from Earth with a spectral type of K0 IV. It has one known planet. The star's reported mass estimate is 1.7 solar masses, which is larger than the Sun's, and its radius of 5.2 solar radii is also larger than the Sun's. Its temperature is 4980 K, cooler than the Sun's. This K-type star is thus both more massive and more distended than the Sun.
The single planet, 6 Lyn b, was discovered in 2008 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 598 Earth masses - a lower bound on its true mass, larger than Earth's and roughly 1.88 times Jupiter's mass. The planet completes one orbit every 920 days.
