Kepler-37 is a yellow dwarf, G-type star, 215.2 light years away in the constellation Lyra. It is host to the exoplanets Kepler-37b, Kepler-37c and Kepler-37d. They all orbit very close to the star. Kepler-37 has a mass of about 80.3 percent of the Sun's and a radius of about 77 percent. It has a temperature similar to that of our Sun, just a bit cooler at 5,417 Kelvin. It has only about half the metallicity of our Sun. With an age of roughly 6 billion years it is slightly older but it is still a main-sequence star.

Planetary system

Kepler-37b is closest to the star. It is the smallest known exoplanet as of February 2013. At 3865 kilometers in diameter it is slightly larger than Earth's moon. It orbits Kepler-37 once every 13 Earth days at a distance close to 0.1 AU and is too small and too close to its star to maintain an atmosphere.

Kepler-37c has around three-quarters the diameter of Earth and it orbits about every 21 Earth days at a distance of nearly 0.14 AU.

Kepler-37d has about twice the diameter of Earth. It has an orbital period of around 40 Earth days at a distance of nearly 0.21 AU.
