Here, 49 such planets from the full catalogue are graphed. The eighth Kepler planet catalog includes 10 new planet candidates that are less than twice the sized of Earth in their stars habitable zone. And they put noise through the process, too, checking how many were marked as transiting planets - so they knew how many planets were likely to be false alarms.

The researchers then put simulated transits into the data and recorded how many were actually picked up by the software - determining how many transits the process might have missed. After vetting, the total came down to about 4,000 candidates, 50 of which were Earth-size and in the habitable zone. As Thompson described, about 34,000 signals were found - both transiting planets and noise that could have come from the camera or star itself. To determine which dimmings of the 200,000 stars observed by Kepler were likely to be planets, the data went through an intensive vetting process. For KOI 7711 and the other planets, the percent the star dimmed let researchers determine its size, and the frequency of the dimming revealed the orbit. That process discovered potential planets like the newly found KOI 7711 (short for Kepler object of interest), an exoplanet that appears very much like Earth - just 1.3 times Earth's radius at an orbit that lets the planet feel about as much radiation as Earth gets from the sun.

To find planets, Kepler uses the transit method: The space telescope tracked stars over a long period of time so scientists could identify when the stars dimmed briefly, which could suggest a planet crossing between the star and Earth.

Now, it's in an extended mission known as K2. Kepler launched in 2009, and completed its primary mission in 2013.

This catalog is the final release of data from Kepler's four-year primary mission, which examined a narrow patch of sky in the Cygnus constellation. 'As a result, this survey catalog will be the foundation for directly answering one of astronomy's most compelling questions: How many planets like our Earth are actually in the galaxy?'ДЄccording to the researchers, Kepler discovered more than 80 percent of all planet candidates and confirmed exoplanets ever found. 'With this catalog we're able to extend out to the longest periods, those periods that are most similar to our Earth,' said Susan Thompson, a Kepler research scientist for the SETI Institute in California and lead author on the new catalog study. NASA/Ames Research Center/Natalie Batalha/Wendy Stenzel Future exoplanet surveys will reveal small planets orbiting further from their stars in the corner marked 'frontier'.

The planets characterized by NASA's Kepler mission (yellow dots) and other surveys split into several different broad planet types.
