Kepler-436 and Its Two Known Planets
Kepler-436 is a star located 1920 light-years away. It is 3 billion years old and has a mass of 0.729 solar masses and a radius of 0.697 solar radii. Its temperature is 4650 K. The star's reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. Two planets are known to orbit this host.
Kepler-436 b is a Neptune-like planet discovered by transit in 2015. It has an orbital period of 64 days and a radius of 2.73 Earth radii. Among the listed planets, Kepler-436 b has the longest year and the largest radius by reported estimates.
Kepler-436 c is a Super-Earth discovered by transit in 2016. It has an orbital period of 16.8 days and a radius of 2.33 Earth radii. Among the listed planets, Kepler-436 c has the shortest year and the smallest radius by reported estimates.
