Kepler-771 and Its Super-Earth
Kepler-771 is a star 4550 light-years away with one known planet. The host star is 3.72 billion years old and has a mass of 1.03 solar masses, a radius of 1.05 solar radii, and a temperature of 5910 K.
The planet, Kepler-771 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-771 b completes an orbit every 8.73 days and has a radius of 1.82 Earth radii. Its reported radius estimate is larger than Earth's. As a Super-Earth, it belongs to a size class that reaches 2.5 times Earth's radius.
