The Kepler-377 system contains 2 exoplanets. It is located 2686.89 light years away from the solar system.
| Mass | 1.07 solar masses |
| Radius | 1.22 solar radiae |
| Temperature | 5949 kelvin |
| Stellar Metallicity | 0.01 decimal exponent |
| Age | 0.3 billion years |
At 2.512 Earth masses, Kepler-377 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.
