Planets of K2-168
K2-168 is a star located 796 light-years away, with a mass of 0.908 solar masses and a radius of 1 solar radii. Its reported temperature is 5290 K, cooler than the Sun's. Two planets orbit this host.
Both planets were found by transit, the method in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. EPIC 205950854 c was discovered in 2019 and K2-168 b in 2018.
EPIC 205950854 c is classified as Earth-like, a size class that stays within 1.5 times Earth's radius. Its radius is 1.31 Earth radii, larger than Earth's, and among the listed planets it has the smallest radius. It completes an orbit in 8.05 days, the shortest year among the listed planets. K2-168 b is a Super-Earth, a class reaching 2.5 times Earth's radius. Its radius is 1.86 Earth radii, larger than Earth's and the largest among the listed planets, and its orbital period of 15.9 days is the longest year among the listed planets.
