WASP-39b - Wikipedia
WASP-39b, officially named Bocaprins, is a "hot Jupiter" extrasolar planet discovered in February 2011 [3] by the WASP project, notable for containing a substantial amount of water in its atmosphere. [1] [4] [5] In addition WASP-39b was the first exoplanet found to contain carbon dioxide in its atmosphere, [6] [7] and likewise for sulfur dioxide.
