1 Ιαν 2020 · All of the giant planet atmospheres contain a temperature minimum located at the tropopause; above that, temperatures increase with height due to the absorption of sunlight by stratospheric aerosols and the methane gas absorption bands (Fig. 5-5). Below the tropopause, temperatures increase with increasing depth as the most efficient means of ...
All the jovian planets have ring systems. Rings are made of many tiny orbiting particles, rocks, and ice balls. Most rings are inside the Roche limit of the host planet. Rings flatten and spread due to collisions, but embedded moonlets and larger exterior moons can keep ring segments in place.
Its rings make Saturn, sixth planet from the Sun, one of the most remarkable objects in the heavens. Brighter than all the stars except Sirius and Canopus, it shines with a steady ashen
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low- boiling point materials ( volatiles ), rather than rock or other solid matter, but massive solid planets can also exist.
Most substantial ring system in the solar system. ~1019 kg of mass, mostly water-ice crystals up to ~m in size. Main rings are ~75,000 - 140,000 km from the center of Saturn, with thicknesses generally a few km, but up to ~1,000 km in some places.
SUMMARY: All four jovian planets are surrounded by a set of rings. These rings are made up of rock, ice, and dust particles that range in size from microscopically small to the size of a house.
The Jovian planets are Jupiter, Saturn, Uranus, and Neptune. They are also called the gas giants or giant planets. There are four major condensable (cloud forming gases) in these planets. The ones with the highest saturation vapor pressure will condense at the highest altitudes.
