Kepler-1850 and Its Lone Known Planet
Kepler-1850 is a star located 816 light-years away, and it hosts one known planet. The star has a reported mass estimate of 0.593 solar masses and a reported radius estimate of 0.587 solar radii, both smaller than the Sun's. Its reported temperature is 4190 K, cooler than the Sun's.
The planet Kepler-1850 b was discovered by the transit method in 2021, when it passed in front of its star from our viewpoint, causing a small dip in observed brightness. It is classified as a Sub-Earth, a size class for planets with a radius smaller than Earth's. Its reported radius estimate is 0.729 Earth radii, smaller than Earth's. Kepler-1850 b completes an orbit, its year, in 1.39 days.
