The Kepler-253 system contains 3 exoplanets. It is located 2735.13 light years away from the solar system.
| Mass | 0.85 solar masses |
| Radius | 0.79 solar radiae |
| Temperature | 5208 kelvin |
| Stellar Metallicity | 0.03 decimal exponent |
| Age | 0.7 billion years |
At 3.307 Earth masses, Kepler-253 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.
