Two of the five planets orbiting a sun-like star called Kepler-62 are squarely in what astronomers call the habitable zone - not too hot, not too cold and possibly bearing water, researchers said in the journal Science.
"These two are our best candidates that might be habitable," said Mr William Borucki, Kepler science principal investigator at NASA's Ames Research Center.
The two planets are slightly larger than ours, and at least a couple of billion years older. The first, 62e, is about 40 per cent larger than Earth.
