Earth 2.0

NASA scientists have discovered a planet similar to ours, which they consider to be “Earth 2.0.”

The planet called Kepler-452b is the smallest planet found so far orbiting the habitable zone of G2-type star, just like our sun, making it the most similar planet to Earth found yet.

"This is the closest thing that we have to another planet like the Earth," Dr. Jon Jenkins, Kepler data analysis lead at NASA's Ames Research Center said. "It would feel a lot like home based on the sunshine."

The remarkable planet is considered to be “Earth’s older, bigger cousin.” It is 60 percent bigger and about 1.5 million years older than Earth.

“It’s awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth,” Jenkins said. “That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.”

Alien life might be possible for the planet, but scientists have to wait a while before answering that question since the planet is 1,400 light years away.
