This artist’s impression shows a view of the surface of a planet orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The planet is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.
