The Kepler-137 system contains 2 exoplanets. It is located 988.18 light years away from the solar system.
| Mass | 0.91 solar masses |
| Radius | 0.8 solar radiae |
| Temperature | 5187 kelvin |
| Stellar Metallicity | -0.02 decimal exponent |
| Age | 4.27 billion years |
At 2.763 Earth masses, Kepler-137 b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes.
