The composition of Jupiter's atmosphere is similar to that of the planet as a whole. [1] Jupiter's atmosphere is the most comprehensively understood of those of all the giant planets because it was observed directly by the Galileo atmospheric probe when it entered the Jovian atmosphere on December 7, 1995.

where R is the ideal gas constant, T is temperature, M is average molecular weight, and g 0 is the gravitational acceleration at the planet's surface. Using the values T=273 K and M=29 g/mol as characteristic of the Earth's atmosphere, H = RT/Mg = (8.315*273)/(29*9.8) = 7.99, or about 8 km, which coincidentally is approximate height of Mt. Everest.
These figures should be compared with the temperature and density of Earth's atmosphere plotted at NRLMSISE-00, which shows the air density dropping from 1200 g/m 3 at sea level to 0.125 g/m 3 at 70 km, a factor of 9600, indicating an average scale height of 70 / ln(9600) = 7.64 km, consistent with the indicated average air temperature over ...
Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere. Jupiter’s Great Red Spot is different from what an Italian astronomer observed in 1665 Skip to ...
Astronomers used the James Webb Space Telescope to newly detect a high-speed jet stream over the equator of Jupiter. Webb telescope spots never-before-seen feature in Jupiter’s atmosphere Skip ...
Storms on Jupiter form ammonia-rich hail — called mushballs — in the atmosphere of the giant planet, new research reveals. Investigators believe these tempests play an important role in ...
The atmosphere has a mass of about 5.15 × 10 18 kg, [2] three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.
The rotation of Jupiter's polar atmosphere is about five minutes longer than that of the equatorial atmosphere. [135] The planet is an oblate spheroid, meaning that the diameter across its equator is longer than the diameter measured between its poles . [ 85 ]
