K2-344 b: A Super-Earth in a Close Orbit
K2-344 is a star 245 light-years away with a mass of 0.51 solar masses and a radius of 0.49 solar radii. Its reported temperature is 4370 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet has been found orbiting this star.
That planet is K2-344 b, a Super-Earth discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods. K2-344 b has an orbital period of 3.36 days and a radius of 1.59 Earth radii. Its reported radius estimate is larger than Earth's.
