What is a major challenge to the potential habitability of Proxima Centauri b despite its location in the habitable zone?
Its orbit is too far from Proxima Centauri to receive enough heat for liquid water.
Proxima Centauri b is a gas giant, making it unlikely to support life.
Intense electromagnetic radiation from its flare star host could strip away its atmosphere.
