The Kepler-404 system contains 2 exoplanets. It is located 2650.10 light years away from the solar system.
| Mass | 0.93 solar masses |
| Radius | 0.88 solar radiae |
| Temperature | 5654 kelvin |
| Stellar Metallicity | -0.04 decimal exponent |
| Age | 0.4 billion years |
At 2.156 Earth masses, Kepler-404 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.
