Kepler-1408 b: A Sub-Earth in a Single-Planet System
Kepler-1408 is a star 1750 light-years away with one known planet. The host star is 2.57 billion years old and has a mass of 1.21 solar masses, a radius of 1.35 solar radii, and a temperature of 6170 K. Its reported mass and radius estimates are both larger than the Sun's.
The system's only cataloged planet is Kepler-1408 b, a Sub-Earth with a radius of 0.89 Earth radii, making it smaller than Earth. It was 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; repeated dips help establish orbital periods. Kepler-1408 b completes an orbit every 3 days.
