Kepler-1957 b: A Sub-Earth Planet
Kepler-1957 is a star located 1500 light-years away. Its reported mass estimate is 0.75 solar masses, its reported radius estimate is 0.752 solar radii, and its reported temperature is 4710 K, making it cooler than the Sun. One planet is known to orbit this star.
That planet, Kepler-1957 b, is a Sub-Earth, a size class for planets smaller than Earth. It was detected 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. Its reported radius estimate is 0.944 Earth radii, smaller than Earth's. The planet completes an orbit every 2.19 days.
