Earth Versus Proxima Centauri b Rotation Rates
Proxima Centauri b is the closest exoplanet to Earth. It is only four light years away. However, since Proxima Centauri b is much closer to its star than Earth, there is a high probability that it is tidally locked, much like our Moon, where one side always faces the Earth.
