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.
