The Kepler-224 system contains 4 exoplanets. It is located 2550.83 light years away from the solar system.
| Mass | 0.82 solar masses |
| Radius | 0.68 solar radiae |
| Temperature | 5018 kelvin |
| Stellar Metallicity | -0.27 decimal exponent |
| Age | 2.29 billion years |
At 2.512 Earth masses, Kepler-224 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.
