Encyclopaedia of exoplanetary systems

This encyclopaedia provides the latest detections and data announced by professional astronomers on exoplanetary systems. It contains objects lighter than 60 masses of Jupiter, which orbit stars or are free-floating. It also provides a database on exoplanets in binary systems, a database on circumstellar disks, an exhaustive bibliography, a list of exoplanet-related meetings, and links to other resources on the subject.

Established in February 1995 Developed and maintained by the exoplanet TEAM

Info

The planets-in-binaries database is now complete for binaries of separations up to 2000au (instead of 500au before that), increasing the database from 330 to 544 systems.

Info

Over 100 new systems have been added to our planets-in-binaries database, representing a 30% increase (a machine-readable table of all systems can be found here)

Info

Additional planet parameters not included in the catalog at https://exoplanet.eu/catalog/
(e.g. the Position Angle (PA) , the ascending node longitude Omega Ω or the projected semi-major axis)
are in the Remarks page of the corresponding planets

Info

After a major update over the last month, we have now reached 7,000 confirmed objects in our database. Our database is currently the most complete in the world.

Info

Today is a day of celebration as we have reached over 6000 validated planets in our database (and counting) !!!! It took 3 years to go from 4000 to 5000 and only one more year to reach 6000, which shows exponential behaviour.
