The red dwarf star sits roughly four point two light-years away from Earth

Located about 4.24 light-years from Earth in the constellation Centaurus, Proxima Centauri is a faint red dwarf star and the nearest stellar neighbour to our Sun. Despite its proximity, it is too dim to be seen with the naked eye and hosts at least two confirmed exoplanets.
