Published by MAST: Mikulski Archive at Space Telescope | National Aeronautics and Space Administration | Catalog Last Checked: May 06, 2026 at 07:23 PM | Dataset Last Updated: April 20, 2026
Launched in 2009, the Kepler Mission is surveying a region of our galaxy to determine what fraction of stars \nin our galaxy have planets and measure the size distribution of those exoplanets. \nAlthough Kepler completed its primary mission to determine the fraction of stars that have planets in 2013, \nit is continuing the search, using a more limited survey mode, under the new name K2. \n\nKOI is the Kepler Objects of Interest catalog listing observed Kepler targets which are flagged as potentially having \nexoplanets but may be false positives caused by other types of transient detection. This catalog is produced by the Kepler\nproject and brought to MAST via NExScI.
