Kepler-1938 b: A Super-Earth in a Distant System
Kepler-1938 is a star located 1370 light-years away, and it hosts one known planet. The star has a mass of 0.646 solar masses, a radius of 0.655 solar radii, and a temperature of 4520 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-1938 b is classified as a Super-Earth, a size class that reaches 2.5 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. Kepler-1938 b has a radius of 1.83 Earth radii, larger than Earth's, and an orbital period of 13.1 days.
