Proxima Centauri b
Proxima Centauri b is the closest known exoplanet to Earth orbiting the red dwarf star Proxima Centauri, a star that is part of a three-star system. More amazingly, Proxima Centauri b lies within the habitable zone of its host star. Any ambition to migrate to the planet, however, must be met with disappointment. Red dwarfs are known to be incredibly erratic, regularly producing stellar winds 2000x more intense than the solar winds Earth receives from the Sun. Additionally, any planet close enough to be near a red dwarf’s habitable zone are tidally locked. Such tidally-locked planets likely suffer the same fate as our Moon, having very hot daytime and extremely cold nights. It is highly unlikely humans can call this place a second home.
