K2-411 and Its Sub-Earth

K2-411 is a star 973 light-years away with one planet. Its mass is 1.02 solar masses and its temperature is 5710 K. Its radius is 1.37 solar radii, which is larger than the Sun's.

The planet K2-411 b was discovered in 2022 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness. Repeated dips help establish orbital periods. K2-411 b completes an orbit every 3.21 days, and its radius is 0.99 Earth radii. That places it in the Sub-Earth size class, which compares radius with Earth's: a Sub-Earth is smaller than Earth.
