Kepler-523 and Its Super-Earth
Kepler-523 is a star located 826 light-years away, and one planet has been detected in its orbit. The host star is 2.45 billion years old, with a mass of 0.93 solar masses and a radius of 0.86 solar radii. Its temperature of 5520 K is cooler than the Sun's. The star's reported mass and radius estimates are both smaller than the Sun's.
The system's only known planet is Kepler-523 b, a Super-Earth 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-523 b completes an orbit every 5.84 days. Its radius of 1.96 Earth radii is larger than Earth's.
