The Kepler-285 system contains 2 exoplanets. It is located 2688.54 light years away from the solar system.
| Mass | 0.82 solar masses |
| Radius | 0.81 solar radiae |
| Temperature | 5411 kelvin |
| Stellar Metallicity | 0.16 decimal exponent |
| Age | 0.6 billion years |
At 2.360 Earth masses, Kepler-285 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.
