Kepler-931 and Its Earth-like Planet
Kepler-931 is a star with a single known planet. Its reported mass estimate is 0.86 solar masses and its reported radius estimate is 0.81 solar radii, both smaller than the Sun's. The star is cooler than the Sun at 5240 K, and it is 4.68 billion years old.
The one planet orbiting this star is Kepler-931 b, an Earth-like planet 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. Kepler-931 b completes an orbit in 8.04 days, and its radius is 1.33 Earth radii, larger than Earth's.
