The Kepler-394 system is known to contain 2 exoplanets in orbit around it. It is located 3453.08 light years away from the solar system.
| Mass | 1.13 solar masses |
| Radius | 1.13 solar radiae |
| Temperature | 6402 kelvin |
| Stellar Metallicity | 0.02 Decimal exponent |
| Age | 0.25 billion years |
At 3.180 Earth masses, Kepler-394 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. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
