Exoplanetary Wiki

This mini-wiki is intended to collect all interesting facts about exoplanetary systems. Planetary System articles are not written in encyclopedic format, but rather in bullet form.

This wiki started out as a set of "System of the Day" posts at the bullitin board of the Extrasolar Visions web site. Concepts and terminology found in that web site are supported in this wiki. Speculations are also welcome.
