Compteur d'exoplanètes | Club d'astronomie de Wittelsheim
En 2024, il y a 36 exoplanètes découvertes qui ont une masse inférieure à 8 masses terrestres. Moyenne sur 2024 : une exoplanète découverte tous les .73 jours.

Merci pour votre question pertinente, pour ce compteur nous nous basons sur la base de données des exoplanètes de <anchor>http://exoplanet.eu/catalog/</anchor> et il y a effectivement toujours un décalage avec la base de donnée de la Nasa. Je suppose que cela doit provenir de leur critères différents de validation des exoplanètes.

## Criteria for inclusion in the catalogue

### Physical criteria

The basic criterion is the mass limit: 60 Jupiter mass.

The former standard limits were13 Jupiter mass, based on the deuterium
burning limit, and 30 Jupitter mass, based on formation scenario. However, the
mass-density-radius distribution (Hatzes & Rauer, 2015) shows a clear
difference between giant planets and stars at 60 Jupier mass.


An additional difficulty comes from the uncertainty in the mass value. We
therefore allow for a 1 sigma uncertainty and chose 60 Mjup + 1 sigma as an
upper mass limit.


We thus finally include planets with masses < 60 Jup up to 1 sigma

### Confidence criteria

Are included planet detections published or submitted to professional
journals or announced by professional astronomers in professional conferences.


### Categories

There are 4 categories of planets, Confirmed, Candidate, Retracted and
Controversial. A planet is considered as Confirmed if it is claimed
unambiguously in an accepted paper or a professional conference.
