16 Cyg B and Its Planet
16 Cyg B is a G5V star 68.9 light-years away. The star is 11.8 billion years old, with a mass of 0.96 solar masses, a radius of 1.17 solar radii, and a temperature of 5670 K. Its reported mass estimate is smaller than the Sun's, its radius estimate is larger than the Sun's, and its temperature is cooler than the Sun's. One planet orbits this host.
That planet, 16 Cyg B b, was discovered by radial velocity in 1996. Its minimum mass is 566 Earth masses, roughly 1.78 times Jupiter's mass and larger than Earth's. Its orbital period is 799 days.
