Miranda size and scale context

Miranda is the smallest and innermost of Uranus' major moons, but Voyager 2 revealed one of the strangest surfaces in the Solar System. Its patchwork coronae, ridges, valleys, and giant fault canyons make it geologically surprising for a moon only about 470 kilometers across. Read its scale context, comparisons, and journey links on the canonical object page.

Moons

Proteus

Proteus is Neptune's largest inner moon, a dark irregular body discovered by Voyager 2 in 1989. It keeps a box-like shape near the threshold where gravity would round it out, while its battered dark surface shows no clear sign of geological remodeling.

Moons

Enceladus

Enceladus is a small icy moon of Saturn whose south polar fractures spray water vapor and ice particles into space. Cassini connected those plumes to a global salty ocean beneath the crust, making Enceladus one of the Solar System's clearest ocean-world targets.
