Kepler-1800 and Its Lone Planet
Kepler-1800 is a star 1140 light-years away with 0.89 solar masses, 0.988 solar radii, and a temperature of 5210 K. This temperature is cooler than the Sun's. The star hosts one known planet.
That planet, Kepler-1800 b, 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. Its orbital period is 4.56 days, and its radius is 0.997 Earth radii. This radius estimate is smaller than Earth's, which places the planet in the Sub-Earth size class.
