Characteristics of the planet

Kepler-440 b is a super-earth with a radius of 1.86 R _⊕ . The planet makes one revolution around the star in 101.1 days.

Inhabitance

The planet is in the habitable zone of its star, theoretically liquid water can exist on the planet, which quite possibly creates quite comfortable conditions for the existence of primitive life forms on the planet's surface.
