19 Ιουλ 2022 · Jovian planets have rings because when they formed, some leftover material was caught by its gravitational field but was too far away for it to be pulled and integrated with the rest of the planet. At least that’s the most plausible theory that astronomers have.
Each of the Jovian planets has several characteristics in common. While Saturn’s bright rings are the most visible and well known, fainter and darker rings have . been seen around Jupiter, Uranus, and Neptune. The Jovian planets also are distinctive for having many moons.
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.
Ring systems. Saturn is the only gas giant planet that has a prominent, easily observable ring system. However, observations have revealed that each of the Jovian planets have ring systems. Jupiter's ring is exceptionally faint. The particles in Jupiter's ring are smaller than those in Saturn's rings and do not reflect light as well.
The gaps in the rings are most probably due to shepherding satellites that orbit in resonance with the rings. The rings are made of myriad individual particles of rock and ice. They are 50,000 miles across and 200 yards deep.
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.
Mass, Density, & Radius. Extreme pressures in Jupiter’s interior cause H to be in liquid & metallic phases. All the Jovian planets have cores of similar mass. Saturn is less massive than Jupiter so its layers of different H phases are more evenly spaced.
