Kepler-240 and Its Two Known Planets

Kepler-240 is a star located 2440 light-years away, and it hosts two known planets. This single star is 4.68 billion years old and has a reported mass of 0.78 solar masses, a radius of 0.74 solar radii, and a temperature of 4920 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.

The two planets were both discovered in 2014 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.

Kepler-240 b is classified as Earth-like and has an orbital period of 4.14 days and a radius of 1.37 Earth radii. Among the listed planets, it has the shortest year and the smallest radius by reported estimates.

Kepler-240 c is classified as a Super-Earth. It orbits once every 7.95 days and has a radius of 2.2 Earth radii, which is larger than Earth's. Among the listed planets, it has the longest year and the largest radius by reported estimates.
