Three Scientists Discover Planet Like Earth

WASHINGTON - Scientists announced the discovery of three planets that could be candidates for human habitation outside the solar system. Unfortunately, the location of the three planets are very far away from the earth.

NASA's Kepler satellite oversees more than 150 thousand stars to identify Earth-like planets. The satellite was discovered three planets. Two planets, Kepler-Kepler-62E and 62F which is the farthest planet to become a candidate for human habitation. Both shaded host of earth-like sun, Kepler62. The third is potentially habitable planet called Kepler-69C.

The planets are the smallest planet ever found in the residential zone, the region where a planet near a star in theory could hold water. Kepler-69c seems less clear in the habitable zone compared to the other two planets. "With all these findings ... are Earth-like planets everywhere," said Kepler scientist, Thomas Barclay reported by CNN.

Kepler-62 is located as far as 1,200 light-years from Earth. Meanwhile, the Kepler-69 located 2,700 light-years away. A light-year is the distance light in a vacuum in one year, nearly 6 trillion miles.

Kepler-62F estimated 40 percent larger than Earth, the planet most like Earth's potential. The possibility of a rocky planet with poles, land, and water.

Meanwhile, Kepler-62E estimated 60 percent larger than the planet Earth and a little closer to their parent planet. Expected, the planet is mostly made ​​up of the oceans.

Other planets, Kepler-69c looks orbiting a sun-like star. The planet is estimated to 70 percent larger than the Earth, and also has a sea water with a depth of thousands of kilometers.
