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.

WASP-39b is in the constellation Virgo, and is about 700 light-years from Earth.[1] As part of the NameExoWorlds campaigns at the 100th anniversary of the IAU, the planet was named Bocaprins, after the beach Boca Prins [de; es] in the Arikok National Park of Aruba.
