Kepler-1218 and Its Earth-Like Planet
Kepler-1218 is a star located 2740 light-years away, and it hosts one planet. The star is 3.8 billion years old and has a mass of 1.06 solar masses, a radius of 1.1 solar radii, and a temperature of 5990 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
The planet, Kepler-1218 b, was discovered in 2016 by the transit method, in which a planet passing in front of its star dims the starlight slightly. It completes an orbit every 22.9 days, and its radius of 1.44 Earth radii is larger than Earth's. That size places it within the Earth-like class, which covers planets up to 1.5 times Earth's radius.
