Kepler-1277 b: A Super-Earth in a Distant System
Kepler-1277 is a star located 1820 light-years away and hosts one planet. The star is estimated to be 5.01 billion years old, with a mass of 0.94 solar masses and a radius of 0.92 solar radii. Its temperature is 5580 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-1277 b, was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods. Kepler-1277 b is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius is 1.6 Earth radii, which is larger than Earth's, and it completes an orbit every 40.8 days.
