 NASA finds 'Earth's bigger, older cousin'
NASA finds 'Earth's bigger, older cousin'

NASA said Thursday that its Kepler spacecraft has spotted "Earth's bigger, older cousin": the first nearly Earth-size planet to be found in the habitable zone of a star similar to our own.

Though NASA can't say for sure whether the planet is rocky like ours or has water and air, it's the closest match yet found.

"Today, Earth is a little less lonely," Kepler researcher Jon Jenkins said.

The planet, Kepler-452b, is about 1,400 light-years from Earth in the constellation Cygnus. It's about 60% bigger than Earth, NASA says, and is located in its star's habitable zone -- the region where life-sustaining liquid water is possible on the surface of a planet.

A visitor there would experience gravity about twice that of Earth's, and planetary scientists say the odds of it having a rocky surface are "better than even."

While it's a bit farther from its star than Earth is from the sun, its star is brighter, so the planet gets about the same amount of energy from its star as Earth does from the sun. And that sunlight would be very similar to Earth's, Jenkins said.

The planet "almost certainly has an atmosphere," Jenkins said, although scientists can't say what it's made of. But if the assumptions of planetary geologists are correct, he said, Kepler-452b's atmosphere would probably be thicker than Earth's, and it would have active volcanoes.
