The Kepler mission has discovered over 2500 exoplanet candidates in the firsttwo years of spacecraft data, with approximately 40% of them in candidatemulti-planet systems. The high rate of multiplicity combined with the low rateof identified false-positives indicates that the multiplanet systems containvery few false-positive signals due to other systems not gravitationally boundto the target star (Lissauer, J. J., et al., 2012, ApJ 750, 131). Falsepositives in the multi- planet systems are identified and removed, leavingbehind a residual population of candidate multi-planet transiting systemsexpected to have a false-positive rate less than 1%. We present a sample of 340planetary systems that contain 851 planets that are validated to substantiallybetter than the 99% confidence level; the vast majority of these have not beenpreviously verified as planets. We expect ~2 unidentified false-positivesmaking our sample of planet very reliable. We present fundamental planetaryproperties of our sample based on a comprehensive analysis of Kepler lightcurves and ground-based spectroscopy and high-resolution imaging. Since we donot require spectroscopy or high-resolution imaging for validation, some of ourderived parameters for a planetary system may be systematically incorrect dueto dilution from light due to additional stars in the photometric aperture.None the less, our result nearly doubles the number of verified exoplanets.
