A simulation of the orbital configuration of the Wolf 1061 system. Wolf 1061 is an inactive red dwarf star, smaller and cooler than our sun, 14 light years away. The planetary habitable zone around the star is marked in green — the colors grade from red (where a planet would be too hot), through green (where the surface of a planet could sustain liquid water), through to blue (where a planet would be too cold).

UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light years away.
