It is about objets lighter than 60 Jupiter masses, which are orbiting stars/brown dwarf or are free floating. It provides also a database about planets in binary systems, and a database about circumstellar disks.

The first bunch of planet candidates are delivered by GAIA DR3 (click on status: candidates at the upper left of the catalog to see them): 63 are astrometric detections and 9 are from radial velocities. GAIA will provide thousands of them in the near future. Thanks to F.Arenou, N. Leclerc, A. Sozzetti (Gaia DPAC), C.Chauvin, F.Roques, Q. Kral & J. Schneider (exoplanet.eu Team)


Our planets in binaries sub-page lists 154 confirmed planets on an S-type orbit (orbiting one of the two stellar components) in <500au separated binaries.


Today, the catalog shows 5014 confirmed planets, 2638 candidates and 821 multiple planets sytems.
