Kepler-1393 b: A Sub-Earth in a One-Planet System
Kepler-1393 is a star located 1780 light-years away, and it hosts exactly one known planet. The star is estimated to be 3.47 billion years old, with a mass of 0.95 solar masses and a radius of 0.92 solar radii. Its temperature is 5700 K. Each of these stellar measurements is smaller or cooler than the corresponding value for the Sun.
The planet, Kepler-1393 b, was discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1393 b completes an orbit every 2.44 days, and its radius is 0.8 Earth radii, smaller than Earth's. That radius places it in the Sub-Earth size class, which compares radius with Earth's rather than indicating composition.
