The K2-37 system contains 3 exoplanets. It is located 586.89 light years away from the solar system.
| Mass | 0.9 solar masses |
| Radius | 0.85 solar radiae |
| Temperature | 5413 kelvin |
| Stellar Metallicity | -0.03 decimal exponent |
| Age | - billion years |
At 3.212 Earth masses, K2-37 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.
