Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima B, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface.

This rocky world is a little more massive than the Earth and is the closest exoplanet to us and it may also be the closest possible abode for life outside the Solar System.
