Proxima Centauri b: A Nearby Habitable-Zone Super-Earth with Uncertain Atmosphere and Water History
To the point
Proxima Centauri b is a nearby exoplanet that orbits a red dwarf every 11.2 days, is a bit more massive than Earth, sits in a zone where water could exist, but its strong stellar radiation could erode its atmosphere and water, making true habitability uncertain.
