A schema of Jupiter's ring system showing the four main components. For simplicity, Metis and Adrastea are depicted as sharing their orbit. (In reality, Metis is very slightly closer to Jupiter.) The rings of Jupiter are a system of faint planetary rings.
The rings are composed of small, dark particles, and they are difficult to see except when backlit by the Sun. Data from the Galileo spacecraft indicate that Jupiter's ring system may be formed by dust kicked up as interplanetary meteoroids smash into the giant planet's small innermost moons.
Jupiter's rings are made of dust from meteor strikes on its moons, and are very faint and hard to see. Learn more about the structure, formation and history of Jupiter's rings, and how they compare to other planetary rings.
16 gru 2004 · Jupiter's main ring is a narrow structure about 6,000 kilometers (about 3,700 miles) in width and about 100,000 times fainter than the planet it encircles. These are the first pictures that NASA's Cassini spacecraft has taken of the ring, a portion of which appears in each frame as an arc opening toward the right.
There are four different components that comprise Jupiter rings: the Halo ring, the Main ring, the Amalthea gossamer ring, and the Thebe gossamer ring. The halo ring is composed of thick particles, the main ring is the brightest but thin and the two gossamer rings are wide and thick but faint.
Discovered in 1979 by NASA's Voyager 1 spacecraft, Jupiter's rings were a surprise, as they are composed of small, dark particles and are difficult to see except when backlit by the Sun. Data from the Galileo spacecraft indicate that Jupiter's ring system may be formed by dust kicked up as interplanetary meteoroids smash into the giant planet's ...
4 dni temu · Jupiter's ring system and inner moons Jupiter's ring system and small inner moons, depicted in a schematic illustration. Impacts of micrometeroids on the four moons provide the dust for the rings. Adrastea and Metis feed the main ring, while Amalthea and Thebe supply material for the gossamer rings.
