The Kepler-339 system contains 3 exoplanets. It is located 2011.20 light years away from the solar system.
| Mass | 0.93 solar masses |
| Radius | 0.8 solar radiae |
| Temperature | 5631 kelvin |
| Stellar Metallicity | 0.033 decimal exponent |
| Age | 4.37 billion years |
At 2.604 Earth masses, Kepler-339 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.
