An international team of researchers has pinpointed which of the more than 4,000 exoplanets discovered by NASA's Kepler mission are most likely to be similar to Earth. The research outlines 216 Kepler planets located within the 'habitable zone' -- the area around a star in which a planet's surface could hold liquid water. Of those they list 20 that are the best candidates to be habitable rocky planets like Earth.
