Kepler-1917 b: A Super-Earth Orbiting a Distant Star
Kepler-1917 is a star 2960 light-years away with one planet known to orbit it. The star has a reported mass estimate of 0.89 solar masses and a reported radius estimate of 0.867 solar radii, both smaller than the Sun's. Its reported temperature is 5230 K, cooler than the Sun's.
The planet Kepler-1917 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; repeated dips help establish orbital periods. Kepler-1917 b has a reported radius estimate of 1.89 Earth radii, larger than Earth's, and an orbital period of 12.9 days.
