The Kepler-213 system contains 2 exoplanets. It is located 2070.89 light years away from the solar system.
| Mass | 1.07 solar masses |
| Radius | 1.2 solar radiae |
| Temperature | 5696 kelvin |
| Stellar Metallicity | 0.157 decimal exponent |
| Age | 1.62 billion years |
At 3.244 Earth masses, Kepler-213 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.
