  2. Rings of Jupiter - Wikipedia

    en.wikipedia.org/wiki/Rings_of_Jupiter

    The age of the ring system is also not known, but it is possible that it has existed since the formation of Jupiter. [9] A ring or ring arc appears to exist close to the moon Himalia's orbit. One explanation is that a small moon recently crashed into Himalia and the force of the impact ejected the material that forms the ring.

  3. Moons of Jupiter - Wikipedia

    en.wikipedia.org/wiki/Moons_of_Jupiter

    A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. [4]

  4. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    Jupiter's moons were classified into four groups of four, based on their similar orbital elements. [204] This picture has been complicated by the discovery of numerous small outer moons since 1999. Jupiter's moons are divided into several different groups, although there are two known moons which are not part of any group (Themisto and Valetudo ...

  5. As I wrote in that article, Jupiter’s main ring is primarily made of dust, and may be due to small particles impacting the two moons Metis and Adrastea; sunlight would push on the dust part

  6. Galilean moons - Wikipedia

    en.wikipedia.org/wiki/Galilean_moons

    The Galilean moons are named after Galileo Galilei, who observed them in either December 1609 or January 1610, and recognized them as satellites of Jupiter in March 1610; [2] they remained the only known moons of Jupiter until the discovery of the fifth largest moon of Jupiter Amalthea in 1892. [3]

    Among the other dwarf planets, Ceres has no known moons. It is 90 percent certain that Ceres has no moons larger than 1 km in size, assuming that they would have the same albedo as Ceres itself. [6] Eris has one large known moon, Dysnomia. Accurately determining its size is difficult: one indicative estimate of its radius is 350 ± 57.5 km. [7]

  8. List of Solar System objects by size - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System...

    The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]

  9. Metis (moon) - Wikipedia

    en.wikipedia.org/wiki/Metis_(moon)

    Metis is the innermost of Jupiter's four small inner moons. It orbits Jupiter at a distance of ~128,000 km (1.79 Jupiter radii) within Jupiter's main ring. Metis's orbit has very small eccentricity (~0.0002) and inclination (~ 0.06°) relative to the equator of Jupiter. [2] [3]
