In the habitable zone of its star, Proxima Centauri, Proxima b encounters bouts of extreme ultraviolet radiation hundreds of times greater than Earth does from the Sun. It doesn’t take into account, for example, whether water actually exists on the planet, or whether an atmosphere could survive at that orbit.
