This artist’s impression shows a view of the surface of Proxima b orbiting Proxima Centauri. Alpha Centauri AB also appears in the image to the upper-right of Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around its star, where the temperature is suitable for liquid water to exist on its surface. Image credit: M. Kornmesser / ESO.
