Kepler-1909 and Its Earth-like Planet
Kepler-1909 is a star located 2490 light-years away, and it hosts one known planet. The star has a mass of 0.819 solar masses, a radius of 0.697 solar radii, and a temperature of 4960 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet Kepler-1909 b is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius. It was discovered in 2021 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; repeated dips help establish orbital periods. Kepler-1909 b has an orbital period of 2.39 days and a radius of 1.09 Earth radii, which is larger than Earth's.
