The Kepler-237 system contains 2 exoplanets. It is located 2145.53 light years away from the solar system.
| Mass | 0.7 solar masses |
| Radius | 0.72 solar radiae |
| Temperature | 4861 kelvin |
| Stellar Metallicity | 0.03 decimal exponent |
| Age | 13.8 billion years |
At 2.573 Earth masses, Kepler-237 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.
