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.
