Kepler-1251 b: A Super-Earth in a Distant System
Kepler-1251 is a star located 2940 light-years away, and it hosts one known planet. The star is 4.79 billion years old, with a mass of 0.92 solar masses and a radius of 0.89 solar radii. Its reported temperature is 5550 K, which is cooler than the Sun's, and its reported mass estimate is smaller than the Sun's.
The planet Kepler-1251 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-1251 b completes an orbit every 45.1 days. Its radius is 1.84 Earth radii, which is larger than Earth's and places it in the Super-Earth size class, a category for planets reaching up to 2.5 times Earth's radius.
