K2-345 b: A Super-Earth in a Distant System

K2-345 is a star located 530 light-years from Earth. It has a mass of 0.56 solar masses and a radius of 0.52 solar radii, both smaller than the Sun's corresponding values. Its temperature is 3780 K, cooler than the Sun. One planet orbits this star.

K2-345 b is a Super-Earth discovered in 2021 by the transit method, which detects the small dip in a star's brightness as a planet passes in front of it. The planet's radius is 2.11 Earth radii, larger than Earth's. Its orbital period is 10.4 days.
