LHS 475 b: A Sub-Earth Around a Nearby Red Dwarf
LHS 475 is an M3.5 V star, a small, cool red dwarf, located 40.7 light-years away. It has one known planet. The star's reported mass estimate is 0.262 solar masses and its reported radius estimate is 0.279 solar radii, both smaller than the Sun's. Its temperature, 3300 K, is cooler than the Sun's.
The planet, LHS 475 b, is classified as a Sub-Earth, meaning its radius is smaller than Earth's. Its radius measures 0.991 Earth radii. It was discovered by the transit method in 2023, and its orbital period is 2.03 days.
