KOI-3284.01 is believed to be the most Earth-like exoplanet to be found so far by the Kepler space probe. It is predicted to have a radius 1.5 times that of Earth's. It is predicted to be located at the proper distance from its star to sustain liquid water. It is also orbiting around a star very similar to our own. If it has a greenhouse effect, its temperature would be estimated at 63.1°F (17.3°C). [1]
