The rings of Jupiter are a system of faint planetary rings. The Jovian rings were the third ring system to be discovered in the Solar System, after those of Saturn and Uranus. The main ring was discovered in 1979 by the Voyager 1 space probe [1] and the system was more thoroughly investigated in the 1990s by the Galileo orbiter. [2]
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.
The boundaries of the halo of the jovian ring, and perhaps other ring structure, are near resonances. ORBITAL resonances, those positions at which periodicities in perturbations are...
1 Σεπ 2010 · Its main ring is located at 1.71R J ≤ r ≤ 1.81R J (the planet's radius R J ≃ 71,398 km) with an optical depth τ ≃ 10 −5. The main ring consists of ‘large bodies’ in the centimeter to meter size range [Showalter et al., 2007] and also a large population of small dust particles in the 0.1 ≤ a ≤ 100 μm size range. The small ...
1 Ιαν 2020 · Seasonal changes in Saturn’s atmosphere are thought to be caused by the rings, which cast shadows on the atmosphere and shield some of the planet from direct sunlight.
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.
Understanding rings appears to be an important step toward understanding the origin and evolution of planetary environments. Most work on the origin of rings has been devoted to Saturn, and somewhat less to the rings of Jupiter, Uranus, and Neptune.
