The Kepler-445 system contains 3 exoplanets. It is located 414.87 light years away from the solar system.
| Mass | 0.18 solar masses |
| Radius | 0.21 solar radiae |
| Temperature | 3157 kelvin |
| Stellar Metallicity | 0.27 decimal exponent |
| Age | 6.61 billion years |
At 3.123 Earth masses, Kepler-445 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.
