NASA Kepler telescope observed an exoplanet, scientists say this is by far the discovery of the Earth-like extrasolar planet.

The existence of the planet has been confirmed, its radius is 1.5 times that of Earth, surrounded by a sun-like stars in stellar livable area. This means that the planet is likely similar to Earth's gravity and surface water resources, which gave birth to the first condition of extraterrestrial life.

The NASA astronomers Natalie - Tubbataha said: "This is very exciting, because this is the first medium that we found around sun-like stars super-Earth planet livable zone."

Fengyun terrestrial planets called "KOI 172.02", said Tubbataha Dr., this finding will potentially close to Earth-like planets beyond our solar system. Currently, the Kepler telescope data show that planets around the star KOI 172.02 run required 242 days a week, and the distance between the stars is three-quarters of the Earth-Sun distance.

U.S. Space Telescope Science Institute astrophysicist Mario - Livio said, this is a major discovery of the planet with the possibility of their birth.

The potential number of exoplanets Kepler mission has found up to 2740 are around 2036 stars. At the same time, in recent years, the probe found the size of the Earth's volume and the number of super-Earth planets gradually increased. Found that the number of planets the size of Earth's volume increased 43%, and increased by 21% the number of planets discovered a super-Earth planets.

California Institute of Technology planetary astronomer John - Johnson said: "If every star has a planet, our galaxy, there are hundreds of billions of planets in the vast majority of the planet around the star and the sun very different. Sometimes few planets will exist in a star system, for example, there are eight planets in the solar system. "
