Proxima Cen b is an intriguing exoplanet orbiting the closest star to our Sun, Proxima Centauri, discovered in 2016 using the clever radial velocity method from Earth's very own European Southern Observatory. This rocky world orbits snugly in its star’s habitable zone, where temperatures might just allow for liquid water—a tantalizing hint for potential alien life or future human visits. Though it’s much smaller than most gas giants, Proxima Cen b packs a punch by being just next door in cosmic terms, only a little over four light years away. Imagine a planet where the night sky is dominated by a red dwarf star, glowing faintly, and every day might feel like a cosmic adventure waiting to unfold!
