The Kepler-280 system contains 2 exoplanets. It is located 2545.19 light years away from the solar system.
| Mass | 0.96 solar masses |
| Radius | 0.89 solar radiae |
| Temperature | 5744 kelvin |
| Stellar Metallicity | 0.121 decimal exponent |
| Age | 4.27 billion years |
At 2.700 Earth masses, Kepler-280 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.
