HEC: Exoplanet and Star Statistics

This page has various statistics for all known exoplanets including confirmed and NASA Kepler candidates. The current number of potential habitable exoplanets and predicted exomoons are shown in red. More details of these objects are available in the main page of the Habitable Exoplanet Catalog (HEC). The PHL's Exoplanet Database has detailed data for all exoplanets, including those potentially habitable.
Last Update: December 5, 2013
Currently Known Exoplanets
Here is a list on the number of confirmed and unconfirmed exoplanets according to the main exoplanet databases. Not all of them list the same number of objects or data depending on their criteria and scope. The PHL' Exoplanets Catalog is almost a mirror of the Extrasolar Planet Encyclopedia but with correction and additions from other databases.
* Kepler candidates not confirmed
