HEC: Exoplanet Statistics

Last Update: October 14, 2015

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 uses the Extrasolar Planet Encyclopedia with many corrections and additions from other sources.

Summary Statistics


This page has statistics for all known exoplanets from the PHL's Exoplanet Database, which includes both confirmed exoplanets and NASA Kepler candidates. The current number of potentially habitable exoplanets and predicted exomoons are shown in red. Some of these numbers are also represented in the Periodic Table of Exoplanets.
