Kepler-1907: A Cool Dwarf with Two Small Worlds
Kepler-1907 is a star located 953 light-years away, and it hosts two known planets. The star is estimated to be 8.91 billion years old, with a mass of 0.673 solar masses and a radius of 0.665 solar radii. Its temperature is 4870 K, making it cooler than the Sun, and both its mass and radius are smaller than the Sun's.
Both planets were 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. Kepler-1907 b is classified as a Sub-Earth, meaning its radius is smaller than Earth's. It has an orbital period of 5.65 days and a radius of 0.87 Earth radii, which is smaller than Earth's. Among the listed planets, Kepler-1907 b has the shortest year and the smallest radius.
Kepler-1907 c is classified as Earth-like, a size class that stays within 1.5 times Earth's radius. It has an orbital period of 14.9 days and a radius of 1.16 Earth radii, larger than Earth's. Among the listed planets, Kepler-1907 c has the longest year and the largest radius.
