The Kepler-240 system contains 2 exoplanets. It is located 2436.15 light years away from the solar system.
| Mass | 0.75 solar masses |
| Radius | 0.74 solar radiae |
| Temperature | 4985 kelvin |
| Stellar Metallicity | 0.18 decimal exponent |
| Age | 0.9 billion years |
At 2.452 Earth masses, Kepler-240 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.
