NASA on Thursday announced the discovery of Kepler-452b, the most Earth-like planet ever found. Located 1,400 light-years from our planet, NASA called it “Earth 2.0,” because it’s the first small, rocky planet discovered in the habitable zone of a G star similar to our sun.
“We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth’s evolving environment,” said Jon Jenkins, the Kepler data analysis lead at NASA’s Ames Research Center.
The planet is 5 percent farther away from its star than Earth is to the sun, making for a slightly longer year of 385 days, but gets similar light because its sun is 20 percent brighter than our own.
