Planets That Do Not Appear in Peer-Reviewed Publications

Unconfirmed Candidates

The archive includes candidate exoplanets on System Overview pages when they are delivered by missions, such as TESS and Kepler (i.e., TOIs and KOIs). We will also occasionally include candidate planets that are of significant interest to the community and public (e.g., Proxima Cen c & d).

Planets with Published Refutations

The following is a list of planets were removed from the Exoplanet Archive based on a published refutation prior to July 2022. Their data are no longer available in the archive.

Note: Archive staff are in the process of restoring data for objects with published refutations that were removed from the archive prior to July 22, 2022. They will be moved from this section to the False Positive Planets section (also on this page) once they're added back to the archive and dispositioned as FPPs.

False Positive Planets

This section lists confirmed planets that were assigned a new disposition, False Positive Planet (FPP), by the Exoplanet Archive after July 2022 based on 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.

Note: Archive staff are in the process of restoring the data for objects with published refutations that were removed from the archive prior to July 22, 2022. They will be moved from the Planets with Published Refutations section (on this page) to this section once they're added back into the archive and dispositioned as FPPs.

Targets of Note

  • Kepler-452 b
  • Kepler-468 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 have added it to the archive's alf Cen System Overview page with the Candidate Planet disposition.
