The Kepler-440 system contains 1 exoplanet. It is located 981.83 light years away from the solar system.
|Mass||0.57 solar masses|
|Radius||0.56 solar radiae|
|Stellar Metallicity||-0.3 decimal exponent|
|Age||1.3 billion years|
At 4.134 Earth masses, Kepler-440 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. Kepler-440 b orbits within the habitable zone of its parent star and could, potentially, be a habitable planet with stable bodies of liquid water on its surface, like Earth.
