    The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 450–500 km radius may be quite porous. [10] For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere.

  3. Moons of Saturn - Wikipedia

    en.wikipedia.org/wiki/Moons_of_Saturn

    These moons all orbit beyond the E Ring. They are: Rhea is the second-largest of Saturn's moons. It is even slightly larger than Oberon, the second-largest moon of Uranus. [53] In 2005, Cassini detected a depletion of electrons in the plasma wake of Rhea, which forms when the co-rotating plasma of Saturn's magnetosphere is absorbed by the moon ...

  4. Moons of Uranus - Wikipedia

    en.wikipedia.org/wiki/Moons_of_Uranus

    The radius of the Uranian Hill sphere is approximately 73 million km. [3] The relative sizes of moons are indicated by the size of their symbols, and the Caliban group of Uranian moons is labeled. Data as of February 2024. Uranus's irregular moons range in size from 120 to 200 km to under 10 km . [43]

  5. 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]

    Pluto's four other moons, Nix, Hydra, Kerberos and Styx are far smaller and orbit the Pluto–Charon system. [5] 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 ...

  8. Galilean moons - Wikipedia

    en.wikipedia.org/wiki/Galilean_moons

    The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with each other. While the Galilean moons are spherical, all of Jupiter's remaining moons have irregular forms because they are too small for their self-gravitation to pull them into spheres.
