Kepler-1817 and Its Super-Earth
Kepler-1817 is a star 2440 light-years away with one known planet. The host star has a mass of 0.801 solar masses and a radius of 0.736 solar radii, both smaller than the Sun's corresponding values. Its temperature is 5470 K, cooler than the Sun's.
The system's only cataloged planet is Kepler-1817 b, a Super-Earth discovered by transit in 2021. It orbits Kepler-1817 every 44.3 days, and its radius of 2.27 Earth radii is larger than Earth's.
