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).

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 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.

Reinstated Targets
The following planets were either confirmed and refuted and then re-confirmed, or initially excluded from the archive until additional data were published.
Note: Click on the planet name to view its System Overview page.
- LkCa 15 b (2015Natur.527..342S)
- HD 1461 c and HD 204313 c (Diaz et al. 2015).
- rho CrB b (a.k.a. HD 143761 b) (Fulton et al. (2016)
- Planets from (Udry et al. 2018):
- GJ 15 A b (Pinamonti et al. 2018)
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.
