Our Nearest Exoplanet, Proxima B, Could Have Large and Chilly Neighbor | Digital Trends
ESO/M. Kornmesser
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.
