K2-220 b: A Super-Earth Orbiting a Star
K2-220 is a star 762 light-years away with 0.91 solar masses, 1.03 solar radii, and a temperature of 5610 K. Its reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet is K2-220 b, a Super-Earth discovered in 2018 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods. K2-220 b completes an orbit every 13.7 days and has a radius of 2.37 Earth radii, larger than Earth's.
