K2-282 and Its Two Planets
K2-282 is a star located 1620 light-years away. It is known to host two planets. The star has a reported mass of 0.95 solar masses and a radius of 0.94 solar radii. Its temperature is 5520 K, and its mass, radius, and temperature are all reported as smaller or cooler than the Sun's.
Both planets were found by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. EPIC 220554210 c was discovered in 2019 and is classified as a Super-Earth. Its radius is 1.6 Earth radii, larger than Earth's, and it orbits in 0.705 days. Among the listed planets, it has the shortest year and the smallest radius by reported estimates.
K2-282 b was discovered in 2018 and is classified as Neptune-like. It has a radius of 2.5 Earth radii, also larger than Earth's, and an orbital period of 4.17 days. Among the listed planets, it has the longest year and the largest radius by reported estimates.
