Kepler-1814 and Its Two Super-Earths
Kepler-1814 is a star 2370 light-years away with a mass of 0.825 solar masses, a radius of 0.754 solar radii, and a temperature of 4960 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. The star is 2.82 billion years old. Two planets orbit this host.
Both Kepler-1814 b and Kepler-1814 c are Super-Earths, a size class reaching 2.5 times Earth's radius. Kepler-1814 b has a radius of 2.37 Earth radii and an orbital period of 2.94 days; among the listed planets it has the largest radius and the longest year. Kepler-1814 c has a radius of 1.76 Earth radii and an orbital period of 0.626 days; among the listed planets it has the smallest radius and the shortest year. Each planet's radius estimate is larger than Earth's. Both planets were detected by the transit method, Kepler-1814 b in 2021 and Kepler-1814 c in 2023, in which a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness.
