Kepler-1281 and Its Super-Earth
Kepler-1281 is a star with one known planet, Kepler-1281 b. The host star's reported mass estimate is 0.87 solar masses, smaller than the Sun's, and its reported radius estimate is 0.83 solar radii, also smaller than the Sun's. Its temperature is 5350 K, cooler than the Sun's, and its age is 4.37 billion years.
Kepler-1281 b is a Super-Earth discovered by transit in 2016, the method in which a planet passing in front of its star produces a small dip in observed brightness. The planet's radius is 1.64 Earth radii, a size larger than Earth's, and it completes an orbit every 3.12 days, the length of its year.
