K2-275: A Cool Star with Two Super-Earths
K2-275 is a star 403 light-years away with two planets orbiting it. The star's reported mass estimate is smaller than the Sun's, and its reported radius estimate is also smaller than the Sun's. Its reported temperature is cooler than the Sun's, at 4780 K.
Both planets are Super-Earths discovered by transit in 2018. K2-275 b has an orbital period of 3.28 days and a radius of 2.34 Earth radii. K2-275 c has an orbital period of 8.44 days and a radius of 2.21 Earth radii. Both planets' reported radius estimates are larger than Earth's.
Among the listed planets, K2-275 b has the shortest year by reported estimates, at 3.28 days, and the largest radius by reported estimates, at 2.34 Earth radii. K2-275 c has the longest year by reported estimates, at 8.44 days, and the smallest radius by reported estimates, at 2.21 Earth radii.
