K2-216 b: A Super-Earth Orbiting a Cool Dwarf
K2-216 is a K5 V star, a main-sequence dwarf cooler than the Sun. It lies 377 light-years away and has a reported mass of 0.7 solar masses, a radius of 0.72 solar radii, and a temperature of 4500 K. One planet orbits this host.
That planet is K2-216 b, a Super-Earth discovered by transit in 2018. Its orbital period is 2.17 days. It has a radius of 1.75 Earth radii and a mass of 8 Earth masses. Its mean density is 8.22 g/cm³, 1.49 times Earth's. Both its radius and its mass are larger than Earth's.
