The new world is20.5 light years away and orbit’s a region with the right temperature which allows liquid water on to the surface.

Scientists believe it Is about 1.5 times larger and five times more massive than the earth, making it the smallest extra solar planet known off. The exciting discovery is that the planet inhabits the habitable zone of parent star Gliese 581.

Also known as the Goldilocks Zone, this is a narrow orbit in which temperatures are not too hot and not too cold, but just right for surface water to exist as liquid.

The habitable planet zone varies according to the output of the stars heat, Gliese 581 is much smaller and colder than the sun. The planet is 14 times closer to its star than the earth to the sun but lies in a region where rivers, lakes and oceans are possible.

One of the pre-requisites for life as we know it on Earth is liquid water. The planet was found by French, Portuguese and Swiss astronomers using the European Southern Observatory’s 3.6 metre telescope at La Silla In Chille.

They look for a “wobble”, this is a method of long distance planet finding on a star caused by the gravity of a large object orbiting it. By measuring this wobble motion, which is shown as shifts in a star’s light spectrum, astronomers can calculate a planets mass and orbit.
