LHS 1140
LHS 1140 is a red dwarf (M dwarf) star roughly 48 light-years from Earth, notable for its unusually quiet activity: its X-ray flux is only about 10x Earth’s, versus Proxima Centauri’s ~400x. This low radiation output makes planets in its habitable zone substantially more favorable to surface life than those around more active red dwarfs.
