Kepler-981 and Its Super-Earth
Kepler-981 is a star located 2,860 light-years away, and it hosts one known planet. The host star has a mass of 0.98 solar masses and a radius of 0.96 solar radii. Its temperature is 5,720 K, and its age is 4.07 billion years.
The planet is Kepler-981 b, a Super-Earth discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-981 b completes an orbit every 4.47 days. Its radius is 2.31 Earth radii, which is larger than Earth's. In size classification, a Super-Earth reaches 2.5 times Earth's radius.
