K2-347 b: A Super-Earth in a Seven-Day Orbit
K2-347 is a star located 1040 light-years away. It has a mass of 0.66 solar masses and a radius of 0.63 solar radii, both smaller than the Sun's, and a temperature of 4600 K, cooler than the Sun's. One planet orbits this star.
That planet, K2-347 b, is a Super-Earth discovered by the transit method in 2021, when it was observed passing in front of its star and dimming its light. It completes one orbit every 7.19 days and has a radius of 2.41 Earth radii, larger than Earth's. Its size classification reflects a radius between 1.5 and 2.5 times Earth's.
