The K2-270 system contains 2 exoplanets. It is located 914.93 light years away from the solar system.
| Mass | 0.85 solar masses |
| Radius | 0.77 solar radiae |
| Temperature | 4877 kelvin |
| Stellar Metallicity | 0.26 decimal exponent |
| Age | - billion years |
At 2.480 Earth masses, K2-270 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.
