Long and tiring search that there is another planet like earth in space are expected to achieve in the next year. It is not possible, this planet could be a new human habitation.
There are at least two criteria of a planet can be called a twin earth, which has the size and the same surface temperature. Actually have discovered thousands of planet candidates that enter the Earth's twin, but uninhabitable by humans.
The planets are called exoplanets, or planets beyond our solar system. These planets are in another orbit, around the sun of their own. Since then, found about 800 other solar systems outside our system.
NASA space telescope, Kepler, discovered more than 2,300 planets potentially habitable since March 2009. Scientists estimate that about 80 percent of the findings will prove true,
In December last year, Kepler discovered planet 2.4 times bigger than Earth. Distance planet with sun far enough.
For planets with the same size and temperature of the Earth, said Mendez, almost undiscovered. He said most of the planets like Earth are very close to their sun, it is impossible to live.
But he is optimistic that 2013 will be a good year for space exploration. If found twin planet Earth, then this will give a remarkable effect on humans. "People look to the sky, just as we look to the ocean. We know oceans have islands and continents are billions of numbers, which can accommodate the whole primitive life and civilization," said Marcy, try likens the search for planets like the search for a new continent.
