EPIC 206317286: A Cool Star With Two Small Worlds
EPIC 206317286 is a star located 1030 light-years away. It has a mass of 0.832 solar masses and a radius of 0.758 solar radii, making it smaller than the Sun. Its temperature of 4750 K is also cooler than the Sun's. Two planets are known to orbit this star.
EPIC 206317286 b is a Sub-Earth with a radius of 0.96 Earth radii. It completes an orbit in 1.58 days, the shortest year among the listed planets. EPIC 206317286 c is a Super-Earth with a radius of 2.09 Earth radii, larger than Earth's. Its orbital period is 17.5 days, the longest year among the listed planets. Both planets were found by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. EPIC 206317286 b was discovered in 2019, and EPIC 206317286 c was discovered in 2022.
