Kepler-181 and Its Two Planets

Kepler-181 is a star 1990 light-years away with two known planets. The host star has a mass of 0.88 solar masses, a radius of 0.85 solar radii, and a temperature of 5380 K, all smaller or cooler than the Sun's corresponding values. Its age is 4.57 billion years.

Both planets were discovered by transit in 2014. Kepler-181 b is classified as Earth-like, with a radius of 1.27 Earth radii and an orbital period of 3.14 days, the shortest year among the listed planets. Kepler-181 c is a Super-Earth with a radius of 1.99 Earth radii and an orbital period of 4.3 days, the longest year among the listed planets. Kepler-181 c's radius is larger than Earth's, and it has the largest radius among the listed planets, while Kepler-181 b has the smallest.
