Astronomers at the European Southern Observatory in Chile have discovered a rocky Earth like planet orbiting Proxima Centauri, the star nearest to our Sun. The planet named Proxima b is about 1.3 times more massive than Earth, orbits it's dim red star every 11 days, and may always keep the same side towards it's sun. Attention grabbing is the fact that Proxima b is at the right distance from it's sun to allow for liquid water on it's surface.
