Gliese 581 c

In April 2007 the Geneva Observatory in Switzerland announced the discovery of a "super-earth" extrasolar planet orbiting the red dwarf star Gliese 581. Dubbed Gliese 581 c, it's been called a super-earth because it is one of the few known extrasolar planets that has a mass near Earth's, and the only one to occupy its sun's "habitable zone."

This image of a rocky and variegated Gliese 581 c with an atmosphere and clouds is purely speculative.
