Kepler-120 and Its Two Super-Earths

Kepler-120 is an M-type main-sequence dwarf located 1270 light-years away, with a spectral type of M0 V. Its mass is 0.72 solar masses, its radius is 0.68 solar radii, and its temperature is 4640 K, making it cooler than the Sun. The star is 3.63 billion years old. Two planets are known to orbit this host.

Both planets are Super-Earths discovered by transit in 2014. Kepler-120 b has a radius of 2.15 Earth radii and an orbital period of 6.31 days. Kepler-120 c has a radius of 1.53 Earth radii and an orbital period of 12.8 days. Among the listed planets, Kepler-120 b has the shortest year and the largest radius, while Kepler-120 c has the longest year and the smallest radius.

A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods. A Super-Earth is a size class reaching 2.5 times Earth's radius.
