This artist’s impression shows a view of the surface of the planet Proxima b orbiting t
he red
dwarf star Proxima Centauri, the closest star to the Solar System. The double star A
lpha 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 Proxima Centauri, wh
ere the temperature is
suitable for liquid water to exist on its surface.
