Kepler-1223 and Its Earth-like Planet
Kepler-1223 is a single-star system located 1500 light-years from Earth, and it hosts one known planet. The star is estimated to be 3.63 billion years old, with a mass of 0.8 solar masses and a radius of 0.75 solar radii. Its reported temperature is 4870 K. The star's reported mass and radius estimates are smaller than the Sun's, and its temperature is cooler than the Sun's.
The system's only listed planet is Kepler-1223 b, an Earth-like world discovered by transit in 2016. It orbits its star every 16.3 days and has a radius of 1.22 Earth radii. That radius estimate is larger than Earth's.
