The Kepler-194 system contains 3 exoplanets. It is located 3581.10 light years away from the solar system.
| Mass | 1.09 solar masses |
| Radius | 1.02 solar radiae |
| Temperature | 6089 kelvin |
| Stellar Metallicity | 0.16 decimal exponent |
| Age | 2.5 billion years |
At 2.891 Earth masses, Kepler-194 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.
