K2-316 and Its Two Known Planets
K2-316 is a star located 367 light-years from Earth, and it hosts two planets. The star has a reported mass of 0.338 solar masses, a radius of 0.353 solar radii, and a temperature of 3390 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's.
Both planets were discovered by transit in 2020. K2-316 b is classified as Earth-like, with a radius of 1.33 Earth radii and an orbital period of 1.13 days. Its radius is larger than Earth's. K2-316 c is classified as a Super-Earth, with a radius of 1.83 Earth radii and an orbital period of 5.26 days. Its radius is also larger than Earth's.
Among the listed planets, K2-316 b has the shortest year and the smallest radius by reported estimates, while K2-316 c has the longest year and the largest radius.
