Hence, Earth - type life around flare stars may be unlikely because their planets must be located very close to dim red dwarfs to be warmed sufficiently by star light to have liquid water (about 0.007 AU for Proxima), which makes flares even more dangerous around such stars.

However, a flare the size of a solar flare occurring on a red dwarf star (such as Proxima Centauri) that is more than ten thousand times dimmer than our Sun would emit about as much or more light as the red dwarf does normally.
