Jupiter's ring system is faint and consists mainly of dust particles from its moons during impacts. Notable moons include the Galilean moons: Io, which has active volcanism; Europa, which likely has a subsurface ocean; Ganymede, the largest moon in the Solar System; and Callisto.

Uranus has a system of narrow, dark rings made of larger pieces of rock and ice. Notable moons include Titania and Oberon; Miranda is interesting due to its geological activity potentially indicating an underground ocean.

Neptune's ring system is faint and is composed mostly of dust and ice particles which is possibly mixed with organic compounds. Its largest moon, Triton, is geologically active and has nitrogen geysers; it also orbits the planet in a retrograde orbit.
