Kepler-1877 and Its Sub-Earth Planet
Kepler-1877 is a star 931 light-years away with a mass of 0.954 solar masses and a radius of 1.02 solar radii, meaning it is slightly less massive than the Sun and very close to the Sun in size. Its temperature is 5460 K, which is cooler than the Sun's. One planet orbits this star.
That planet, Kepler-1877 b, was discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1877 b completes an orbit every 2.38 days and has a radius of 0.624 Earth radii, smaller than Earth's. This places it in the Sub-Earth size class, which compares radius with Earth's: a Sub-Earth is smaller than Earth.
