GJ 341 and Its Planet

GJ 341 is a small, cool red dwarf of spectral type M1, located 34.1 light-years away. Its reported mass estimate is 0.48 solar masses, smaller than the Sun's, and its reported radius estimate is 0.507 solar radii, also smaller than the Sun's. Its reported temperature is 3770 K, cooler than the Sun's. One planet is known to orbit this star.

That planet, GJ 341 b, was discovered by transit in 2025. Its reported radius estimate is 0.88 Earth radii, smaller than Earth's, placing it in the Sub-Earth size class, which compares radius rather than composition. Its mass is reported as an upper limit of 4 Earth masses, and its orbital period is 7.58 days.
