Kepler-400 and Its Two Known Planets
Kepler-400 is a star 2760 light-years away with an age of 3.63 billion years. Its mass is 1.08 solar masses and its radius is 1.12 solar radii, and its temperature is 5980 K. The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. Two planets are known to orbit this host.
Kepler-400 b is a Super-Earth discovered by transit in 2014. It completes an orbit in 9.02 days and has a radius of 1.65 Earth radii, which is larger than Earth's. Among the listed planets, it has the shortest year and the largest radius by reported estimates.
Kepler-400 c is an Earth-like planet also discovered by transit in 2014. Its orbital period is 17.3 days, and its radius is 1.49 Earth radii, larger than Earth's. Among the listed planets, it has the longest year and the smallest radius by reported estimates.
