A general catalogue of exoplanets

Home Catalogue Columns in the catalogue News and updates Datasources Mistakes on www.exoplanet.eu and Kepler website Contact me

This website aims to provide a comprehensive database of all the exoplanets that have been discovered since 1995.
Most websites that show a database on exoplanets just have a selection like transiting exoplanets, confirmed exoplanets, kepler exoplanets etc.
This database does not focus on the confirmed/unconfirmed distinction as there is no agreed definition for those categories yet.
The total counter for all exoplanets of any type is on 7462 at the moment (04-07-2018).
The total collection of all records can be found in the catalogue. Newly added records are in bold.

Data for this inclusive database come from 5 websites (please see the data sources for explanation):

www.exoplanet.eu the exoplanet database maintained by the Paris Astronomical Institute
Kepler archive the Kepler website where the databases for the confirmed, unconfirmed and the K2 candidate exoplanets are maintained
CDS the general exoplanet database maintained by the Centre de Donnee Stellaires from the University of Strasbourg
Arxiv newly reported exoplanets in Arxiv publications
GCVS variable stars with the status Ep or Ep: (total 36) from the General Catalogue of Variable Stars


All databases mentioned above are compared with the existing database that was collected in the course of the last few years
to find the ones that are not in my database yet.
Identification is done based on coordinates, not on exoplanet name because that is impossible.
After extensive analysis that this is indeed a new exoplanet, it will be added to my database, including all the identification data,
usually data are taken from the CDS as this is the most accurate database. See Datasources for more details

What is not included:
- exoplanets for which no coordinates are given (several 'anonymous' exoplanets on exoplanet.eu)
- exoplanets that are reported in publications as exoplanets but for which no observations or discovery publication can be found
(and probably are just typos of existing exoplanets)
- exoplanets labeled as false positive in Kepler or 'err' in the CDS

The number of exoplanets in these databases is as follows (on 04-07-2018):

Kepler confirmed
Kepler unconfirmed
K2 candidates
Exoplanets discovered by amateur astronomers

because of the many double entries the total number of exoplanets amounts to: 7462
