False Positive Planets

This section lists confirmed planets that were assigned a new disposition, False Positive Planets (FPP), by the Exoplanet Archive after July 2022 based published refutations. The objects have been removed from the Planetary Systems and Planetary Systems Composite Parameters tables, but their data are still available on their respective System Overview pages. Demoted K2 objects will continue to appear in the K2 Planets and Candidates table (with an updated disposition of False Positive Planet), but not in the K2 Confirmed Names table.

Targets of Note

• Kepler-452 b
• Kepler-468 b, Kepler-470 b, Kepler-628 b, Kepler-840 b, Kepler-854 b, and Kepler-1415 b: These objects were dispositioned as false positives by the Kepler False Positive Working Group (KFPWG) in the Kepler Objects of Interest (KOI) DR 25 Supplemental release. In the absence of a peer-reviewed, published refutation, the objects remain listed as confirmed planets in the Exoplanet Archive.
• proxima Centauri c: This promising candidate has been noted by a number of publications, but as of yet there is no published, peer-reviewed confirmation of the planetary nature of the signal. We are monitoring the literature and will update the status of proxima Centauri c as soon as it becomes clear.
