query: Does Jupiter have an atmosphere?
passage: Atmosphere of Jupiter
The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water. Although water is thought to reside deep in the atmosphere, its directly measured concentration is very low. The nitrogen, sulfur, and noble gas abundances in Jupiter's atmosphere exceed solar values by a factor of about three.[2]
passage: Titan Winged Aerobot
Titan is the only moon with an atmosphere, and its atmosphere is the only known nitrogen-rich atmosphere in the Solar System. The observations from Voyager and Cassini–Huygens shows that its atmosphere is denser than earth with the atmospheric pressure of 1.45 atm . It is 1.9 times as massive as Earth overall.
