K2-286 and Its Super-Earth
K2-286 is an M0 V star, a small, cool red dwarf, located 248 light-years away. It has a mass of 0.64 solar masses and a radius of 0.62 solar radii, both smaller than the Sun’s, and a temperature of 3930 K, cooler than the Sun’s. One planet orbits this star.
That planet, K2-286 b, is a Super-Earth discovered by transit in 2018. It has an orbital period of 27.4 days and a radius of 2.1 Earth radii, larger than Earth’s.
