K2-227: A Cooler, Smaller Sun with One Super-Earth
K2-227 is a star located 611 light-years away, with a reported mass of 0.962 solar masses, a radius of 0.934 solar radii, and a temperature of 5490 K. Its radius estimate is smaller than the Sun's, and its temperature is cooler than the Sun's. One planet orbits this host.
That planet is K2-227 b, a Super-Earth discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-227 b has an orbital period of 13.6 days and a radius of 1.67 Earth radii. Its radius estimate is larger than Earth's, and its size class places it within the Super-Earth range.
