Kepler-37c is an exoplanet discovered by the Kepler space telescope in February 2013.^[3] With an orbital period of 21 days,^[4] it is located 209 light-years away, in the constellation Lyra.

Host star

The planet orbits a (G-type) star similar to the Sun, named Kepler-37, orbited by a total of four planets. The star has a mass of 0.80 M_☉ and a radius of 0.79 R_☉. It has a temperature of, 5417 K and is 5.66 billion years old. In comparison, the Sun is 4.6 billion years old,^[5] and has a temperature of 5778 K.^[6]

The star's apparent magnitude, or how bright it appears from Earth's perspective, is 9.71. Therefore, it is too dim to be seen with the naked eye.
