Kepler might expect to see an Earth-like planet transit a Sun-like star roughly once every 365 days. The scientists observing Kepler-186f saw it pass before its parent star at more than twice that frequency. Remember: Keplers only been in orbit since 2009. In a few years, we could be up to our ears in planets that meet all three of the criteria laid out above. In fact, astronomers have made it clear that they expect this. Its really just a matter of time. io9/astronomers-have-found-the-first-earth-sized-habitable-1564345380?utm_campaign=socialflow_io9_facebook&utm_source=io9_facebook&utm_medium=socialflow
