The Kepler-126 system contains 3 exoplanets. It is located 774.30 light years away from the solar system.
| Mass | 1.18 solar masses |
| Radius | 1.36 solar radiae |
| Temperature | 6239 kelvin |
| Stellar Metallicity | -0.07 decimal exponent |
| Age | 3.39 billion years |
At 2.926 Earth masses, Kepler-126 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.
