Kepler-1338 b: A Sub-Earth in a Close Orbit
Kepler-1338 is a single-star system located 2460 light-years away. Its host star is 3.8 billion years old, with a mass of 1.04 solar masses, a radius of 1.05 solar radii, and a temperature of 5910 K. One planet orbits this star.
That planet is Kepler-1338 b, a Sub-Earth discovered by the transit method in 2016. A transit occurs when a planet crosses in front of its star from our viewpoint, dimming the star's light slightly. Kepler-1338 b has a radius of 0.92 Earth radii, placing it below Earth's size, and it completes an orbit in 0.935 days.
