The Kepler-357 system contains 3 exoplanets. It is located 2245.82 light years away from the solar system.
| Mass | 0.79 solar masses |
| Radius | 0.83 solar radiae |
| Temperature | 5036 kelvin |
| Stellar Metallicity | 0.18 decimal exponent |
| Age | 13.8 billion years |
At 4.039 Earth masses, Kepler-357 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.
