Details
Puck is the largest of Uranus' lesser inner moons, discovered in Voyager 2 images ahead of the spacecraft's 1986 Uranus flyby. It orbits Uranus in less than one Earth day, between the rings and Miranda.
Voyager 2 discovered Puck in images taken during its 1986 encounter with Uranus. At roughly 160 kilometers across, it is the largest of the planet’s lesser inner moons but far smaller than Miranda, the smallest of the five major satellites. Puck completes an orbit in less than one Earth day within Uranus’s compact inner moon system.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
