Kepler-239 and Its Two Planets

Kepler-239 is a star located 2110 light-years away. It has an age of 3.31 billion years, a mass of 0.84 solar masses, a radius of 0.77 solar radii, and a temperature of 5010 K. Its reported mass, radius, and temperature are all smaller or cooler than the Sun's corresponding values. Two planets are known to orbit this host.

Both planets were discovered by transit in 2014. Kepler-239 b is a Super-Earth with an orbital period of 11.8 days and a radius of 2.33 Earth radii, larger than Earth's. Kepler-239 c is Neptune-like, with an orbital period of 56.2 days and a radius of 2.51 Earth radii, also larger than Earth's. Among the listed planets, Kepler-239 b has the shortest year and the smallest radius by reported estimates, while Kepler-239 c has the longest year and the largest radius.
