Kepler-1123 is a star located 2300 light-years away. One planet orbits it. The host star is 5.13 billion years old and has a mass of 0.93 solar masses, a radius of 0.9 solar radii, and a temperature of 5500 K. Its reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet, Kepler-1123 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. It is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Kepler-1123 b has a radius of 1.67 Earth radii, larger than Earth's, and completes an orbit in 4.34 days.
