his infographic compares the orbit of the planet around P
roxima Centauri (Proxima b) with
the same region of the Solar System. Proxima Centauri is smaller and cooler than t
he Sun and the
planet orbits much closer to its star than Mercury. As a result it lies wel
l within the habitable zone,
where liquid water can exist on the planet

s surface.
