Kepler-1227 and Its Super-Earth
Kepler-1227 is a single-star system 2030 light-years away, and it hosts one known planet. The star is 4.17 billion years old and has a mass of 0.97 solar masses, a radius of 0.95 solar radii, and a temperature of 5750 K.
The planet is Kepler-1227 b, a Super-Earth discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, dimming the observed brightness. Kepler-1227 b orbits every 94.3 days and has a radius of 2.29 Earth radii, larger than Earth's radius.
