Kepler-1440 and Its Lone Planet
Kepler-1440 is a star located 3640 light-years away, and it hosts one known planet. The star is 4.47 billion years old and has a mass of 0.98 solar masses and a radius of 0.96 solar radii. Its temperature of 5700 K is cooler than the Sun's.
The planet Kepler-1440 b was discovered in 2016 by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. It is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius. Its radius of 1.26 Earth radii is larger than Earth's, and it completes an orbit every 39.9 days.
