The search for planets beyond our solar system has brought an historic discovery: a planet slightly larger than Earth orbiting a star called Proxima Centauri. At just over 40 trillion kilometers from the Sun, Proxima Centauri is our closest stellar neighbor. Does its planet have a climate, or even life?

Trivia, insights & behind the scenes
Proxima Centauri b was discovered in 2016 using the Doppler method — scientists detected the star's tiny wobble from the planet's gravitational pull, not by seeing the planet directly.
The 'pale red dot' name deliberately echoes Carl Sagan's 'pale blue dot' — this documentary positions Proxima b as Earth's mirror image rather than just another exoplanet statistic.
