Gliese 341 b, also known as TOI-741 b, is a confirmed exoplanet orbiting Gliese 341, a red dwarf star located 33.9 light-years from Earth in the constellation Carina, visually close to the False Cross asterism. Having a radius of 0.92 R🜨 and an estimated mass of 0.72 M🜨, it is classified as a sub-Earth. It was discovered in 2024 via transit observations and analyzed by James Webb Space Telescope in the search for an atmosphere.
