Proxima Centauri b
Proxima Centauri b is a planet orbiting Proxima Centauri, the closest known star to our Sun, about 4.24 light-years away. It’s roughly Earth-sized and lies within the star’s habitable zone, where conditions might allow liquid water to exist. However, Proxima Centauri is a red dwarf star that can produce intense solar flares, which could challenge the planet’s ability to support life. While its exact nature and atmosphere are still unknown, Proxima Centauri b is a significant discovery because of its proximity and potential to study worlds outside our solar system.
