Extrasolar planet Gliese 581c. Computer artwork of Gliese 581c and two asteroids (right). This planet is one of three that orbit the star Gliese 581 (not seen). Gliese 581c is the most Earth-like alien planet yet discovered. It lies in the star's habitable zone, a region around a star where the surface temperature of a planet is suitable for liquid water. Gliese 581 lies about light years from Earth in the constellation Libra.
