Kepler-1798 and Its Super-Earth
Kepler-1798 is a star 1290 light-years from Earth with a single known planet, Kepler-1798 b. The host star has a reported mass estimate of 0.65 solar masses and a reported radius estimate of 0.641 solar radii, both smaller than the Sun's. Its reported temperature is 4160 K, cooler than the Sun's.
Kepler-1798 b is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its reported radius estimate is 2.31 Earth radii, larger than Earth's. The planet completes an orbit every 16.9 days. 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.
