Kepler-1228 and Its Super-Earth
Kepler-1228 is a star 1680 light-years away with one known planet, Kepler-1228 b. The discovery was made by the transit method in 2016. The star is 5.13 billion years old and has a mass of 0.78 solar masses and a radius of 0.74 solar radii. Its temperature is 5060 K, cooler than the Sun, and both its mass and radius are smaller than the Sun's.
Kepler-1228 b is classified as a Super-Earth, a size class that reaches up to 2.5 times Earth's radius. The planet's radius is 1.54 Earth radii, larger than Earth's, and it completes an orbit in 0.577 days.
