Kepler-1309 and Its Super-Earth
Kepler-1309 is a star with one known planet. The star is estimated to be 4.27 billion years old, with a mass of 0.85 solar masses and a radius of 0.8 solar radii. Its temperature is 5240 K. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet Kepler-1309 b was discovered in 2016 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. Repeated dips help establish orbital periods. Kepler-1309 b is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius is 2.37 Earth radii, larger than Earth's, and its orbital period is 28.8 days.
