They range from gas behemoths that dwarf Jupiter to a dainty body only about six times bulkier than Earth. Since the first one was detected a decade ago, the number of confirmed planets outside our solar system has climbed to more than 160, according to this database from Jean Schneider of the Paris Observatory in France. The Extrasolar Planets Encyclopaedia compiles vital statistics for each world, including mass and orbital axis, along with data for its parent star, such as spectral type and distance from Earth. The reports come from papers or preprints, conferences, and other planet-tallying sites. Visitors can also peruse a separate rundown of unconfirmed and retracted objects.
