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.

2024年10月24日 · WASP-39 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.28 Jupiters, it takes 4.1 days to complete one orbit of its star, and is 0.0486 AU from its star. Its discovery was announced in 2011.

2022年11月22日 · The exoplanet WASP-39 b is also known as Bocaprins, a name bestowed by the International Astronomical Union for a scenic beach in Aruba. NASA's James Webb Space Telescope provided the most detailed analysis of an exoplanet atmosphere ever with WASP-39 b analysis released in November 2022.
