K2-71 b: A Super-Earth Orbiting a Cool Red Star

K2-71 is a star located 500 light-years away. It has a mass of 0.472 solar masses, a radius of 0.474 solar radii, and a temperature of 3500 K. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.

One planet orbits this host: K2-71 b, a Super-Earth discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness that can help establish orbital periods. K2-71 b completes an orbit every 6.99 days and has a radius of 2.15 Earth radii. Its reported radius estimate is larger than Earth's.
