The Kepler-249 system contains 3 exoplanets. It is located 621.00 light years away from the solar system.
| Mass | 0.51 solar masses |
| Radius | 0.48 solar radiae |
| Temperature | 3568 kelvin |
| Stellar Metallicity | -0.34 decimal exponent |
| Age | 3.09 billion years |
At less than 1.5 Earth masses, Kepler-249 b is a terrestrial planet, much like the terrestrial planets we find in our solar system, namely Mercury, Venus, Earth and Mars.

At 2.891 Earth masses, Kepler-249 c 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.
