NASA scientists report the discovery of LHS 475 b, an exoplanet almost identical in size and mass to Earth, and the first to be confirmed by the James Webb Space Telescope.
LHS 475 is a red dwarf star with about a quarter of our Sun’s mass and radius, located relatively close in our stellar neighbourhood at 41 light years away. Astronomers have now confirmed that the system contains at least one known exoplanet, designated LHS 475 b.
