Kepler-1331 b: A Close-Orbiting Earth-Sized World
Kepler-1331 is a star located 1040 light-years away. It is 4.17 billion years old and has a mass of 0.72 solar masses and a radius of 0.69 solar radii. Its temperature is 4510 K, cooler than the Sun. The star's reported mass and radius estimates are both smaller than the Sun's. One planet orbits this host.
That planet is Kepler-1331 b, an Earth-like world discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint. Kepler-1331 b completes an orbit every 0.789 days, and its radius is 1.05 Earth radii.
