Proxima Centauri b: An Earth-like World in the Habitable Zone of the Nearest Star

To the point

Proxima Centauri b is a rocky, Earth-like planet about 4.24 light-years away that orbits the nearest star, Proxima Centauri, every 11.2 days at roughly 7 million kilometers with a mass about 1.3 times Earth in the red dwarf’s habitable zone, likely tidally locked, a discovery led by Guillem Anglada-Escudé, and while future telescopes may image it, its habitability and the possibility of travel remain uncertain.
