The Kepler-250 system contains 3 exoplanets. It is located 2480.69 light years away from the solar system.
| Mass | 0.83 solar masses |
| Radius | 0.81 solar radiae |
| Temperature | 5160 kelvin |
| Stellar Metallicity | 0.02 decimal exponent |
| Age | 13.2 billion years |
At 1.507 Earth masses, Kepler-250 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.
