Earth’s twin

According to Abel Méndez, a researcher with the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo,  the race is on to find Earth’s twin, the elusive Earth-size planet in the habitable, or “Goldilocks,” zone around a star where liquid water can exist—and experts believe we may hit the cosmic jackpot soon.
“I think we are very close to finding a potential ‘Earth 2.0’—possibly next year,”  Abel Méndez,said.
In 2012 astronomers came closer than ever to zeroing in on an earthly doppelganger, or what Méndez refers to as “terran” planets—or at the very least a planet considered potentially habitable.
“However, we are far from confirming the habitability of any of these planets until we have the capability to observe their atmosphere, but that will take many years,” Méndez said. “The big goal now is to find an Earth-size planet in [its] star’s habitable zone—something more similar to Earth.”
Are we close to Earth’s twin?
