Astronomers hunting for another Earth have found the closest match yet, a potentially rocky planet circling its star at the same distance as the Earth orbits the Sun, NASA has said.

Named Kepler 452b, the planet is about 60 percent larger than Earth. It could have active volcanoes, oceans and sunshine like ours, twice as much gravity and a year that lasts 385 days, scientists said on Thursday.

“Today we are announcing the discovery of an exoplanet that, as far we can tell, is a pretty good close cousin to the Earth and our Sun,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington.

“This is about the closest so far, and I really emphasize the ‘so-far,’” he added, describing Kepler 452b as “the closest twin,” or “Earth 2.0.”

The planet was detected by the US space agency’s Kepler Space Telescope, which has been hunting for other worlds like ours since 2009.

 This planet sits squarely in the Goldilocks zone – where life could exist because it is neither too hot nor too cold to support liquid water, the US space agency said.

“Today the Earth is a little less lonely,” said Jon Jenkins, Kepler data analysis lead scientist at NASA’s Ames Research Center in Moffett Field, California.

Kepler 452b’s star is 1.5 billion years older, four percent more massive and 10 percent brighter than our sun.
