The planet exists outside our solar system and lies in a 'habitable zone', meaning that it isn't too near to its sun to dry out or too far away to be frozen. The planet, Gliese 667Cc, orbits around a red dwarf star (common stars in the neighbourhood of the sun, usually hosting planets called gas giants, which are not composed of rock matter), 22 light years away from the earth. Gliese 667Cc is a solid planet with roughly four and a half times the mass of Earth and receives less that ten percent less light from its red dwarf star than the Earth gets from the sun. The planet still receives nearly the same amount of energy as the Earth, which means that water could be liquid and surface temperatures could be similar to that on Earth.
