Kepler-1801 and Its Two Planets
Kepler-1801 is a star 2740 light-years away with a mass of 0.936 solar masses, a radius of 0.981 solar radii, and a temperature of 5740 K. Two planets are known to orbit it: Kepler-1801 b and Kepler-1801 c.
Both planets are Neptune-like, a size class that reaches four times Earth's radius, and both were found by the transit method, in which a planet passing in front of its star dims the star's observed brightness. Kepler-1801 b was discovered in 2021 and has a radius of 2.71 Earth radii, larger than Earth's, with an orbital period of 10.4 days. Kepler-1801 c was discovered in 2023 and has a radius of 2.91 Earth radii, also larger than Earth's, with an orbital period of 117 days.
Among the listed planets, Kepler-1801 b has the shortest year, at 10.4 days, and the smallest radius, at 2.71 Earth radii. Kepler-1801 c has the longest year, at 117 days, and the largest radius, at 2.91 Earth radii.
