Our Nearest Exoplanet, Proxima B, Could Have Large and Chilly Neighbor | Digital Trends

Alpha Centauri sure has an interesting SF history; it went from “of course it has Earth analogues, it’s our closest stellar neighbor” to “multiple star systems can’t host planets” and now back again to “we might just be able to live there”

Our nearest exoplanet discovered so far is Proxima b, which orbits the star Proxima Centauri located 4.2 light-years from Earth. Orbiting a red dwarf, Proxima b sits in the habitable zone, meaning it could host liquid water on its surface, and is roughly the same size as Earth, making it an intriguing target for dreams of planetary colonization. It was previously believed that Proxima b was the only world hosted by Proxima Centauri.
