The Kepler-176 system contains 4 exoplanets. It is located 1719.89 light years away from the solar system.
| Mass | 0.79 solar masses |
| Radius | 0.89 solar radiae |
| Temperature | 5232 kelvin |
| Stellar Metallicity | 0.16 decimal exponent |
| Age | 13.7 billion years |
At 2.636 Earth masses, Kepler-176 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.
