Kepler-1173 and Its Lone Planet
Kepler-1173 is a star located 1230 light-years away. It hosts one known planet. The star is estimated to be 4.79 billion years old, with a mass of 0.86 solar masses and a radius of 0.82 solar radii. Its temperature is 5250 K. These figures indicate a star somewhat smaller, less massive, and cooler than the Sun.
The single known planet is Kepler-1173 b, 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 Sub-Earth, meaning its radius is smaller than Earth's. Its radius is 0.89 Earth radii, and it completes an orbit in 0.77 days.
