The Kepler-441 system contains 1 exoplanet. It is located 874.11 light years away from the solar system.
| Mass | 0.57 solar masses |
| Radius | 0.55 solar radiae |
| Temperature | 4340 kelvin |
| Stellar Metallicity | -0.57 decimal exponent |
| Age | 1.9 billion years |
At 3.339 Earth masses, Kepler-441 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. With a mass below 5 Earth masses, and a semi-major axis of 0.64 astronomical units, which is outside the habitable zone of Kepler-441, Kepler-441 b is likely an icy world.
