K2-202 b: A Super-Earth in a Three-Day Orbit
K2-202 is a star located 980 light-years from Earth. It has 0.971 solar masses and 0.911 solar radii, making its reported radius estimate smaller than the Sun's. Its temperature is 5490 K, cooler than the Sun's. One planet orbits this host: K2-202 b.
K2-202 b was 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. That period is 3.41 days, the time the planet takes to complete one orbit. With a radius of 2.3 Earth radii, K2-202 b is classified as a Super-Earth - a size class that reaches 2.5 times Earth's radius - and its reported radius estimate is larger than Earth's.
