Kepler-823 and Its Super-Earth
Kepler-823 is a star 4530 light-years away with one known planet. The host star is 4.47 billion years old and has a mass of 0.98 solar masses and a radius of 0.96 solar radii. Its temperature of 5640 K is cooler than the Sun's.
The planet Kepler-823 b is a Super-Earth discovered by transit in 2016, when it was detected passing in front of its star and causing a small dip in observed brightness. It completes an orbit every 4.17 days. Its radius of 1.57 Earth radii is larger than Earth's, placing it in a size class that compares radius with Earth's; a Super-Earth reaches 2.5 times Earth's radius.
