“350 have already been discovered exoplanetas, but too nearby or removed of their own sun”.
The astronomers who look for planets similar to the Earth found two very similar ones to ours: One is of similar size. Other is in the precise place.
European investigators announced the discovery not only of the exoplaneta – a planet out of the solar system - smaller that one knows, called Gliese 581 - and, but they understood that an already well-known nearby planet, Gliese 581-d, was in the most habitable area of his system.
“ The maximum target of the investigation exoplanetaria current is the detection of a rocky planet similar to the ground in the habitable area”, affirmed Michel Mayor, astrophysicist of the University of Geneva.

Gliese 581 - and has scarcely 1,9 times the size of the Earth. Other exterior planets to our solar system approach the dimensions of Jupiter, inside which a thousand of Earths would fit.
Gliese 581 - and is close to his star, for which the heat is excessive as to allow the life. Nevertheless, it indicated Major, his discovery in a solar system at 20,5 light years of the Earth is a “good example of that we are progressing in the detection of planets similar to the Earth.
The scientists also discovered that the orbit of the planet Gliese 581-d, known from 2007, is in the “habitable area”, a region around a star that allows the existence of liquid water in the surface, it revealed Major.
