An extrasolar planet catalog and reference guide. An extrasolar planet (or exoplanet) is a planet that is outside our solar system. These planets orbit other stars. The first exoplanets were discovered in the mid 1990's, but exoplanet hunting began in earnest only recently. This catalog is kept up-to-date with the current count of exoplanets, all the latest data for each exoplanet, and the data for every parent star.

With the home screen widget, watch the exoplanet count skyrocket in the coming months as new data become available. The count at the moment is just above 500. The count by 2012 could approach 1000!

Watch each new exoplanet's mass, radius, and period trend toward that of our very own Earth. Soon astronomers will find exoplanets resembling Earth in many ways!
