Kepler-440 and Its Super-Earth
Kepler-440 is a star 982 light-years away with one known planet. The host star is 1.3 billion years old and has a mass of 0.575 solar masses and a radius of 0.559 solar radii. Its temperature is 4130 K, cooler than the Sun's. Its mass and radius are both smaller than the Sun's.
The planet Kepler-440 b was discovered in 2015 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. It is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Kepler-440 b has a radius of 1.86 Earth radii, larger than Earth's, and an orbital period of 101 days.
