The list of exoplanetary candidates has grown 219 (image credit: NASA/JPL-Caltech).

A full re-examination of the Kepler Space Telescope's data has revealed an additional 10 new planets that are near-Earth size and in their host-star's habitable zone. Even more interesting, follow-up studies on all of the rocky planets discovered by Kepler (thousands) to-date show that smaller planets come in two sizes. They are either 1.5 Earth Radii and smaller, or 2 Earth Radii and larger. The Kepler Space Telescope held its primary data collection from 2009 to 2013. The total number of planets confirmed in that data is 2335. Adding in planets found by other telescopes, the current number of known planets orbiting other stars is 3610.
