Uranus' Rings

The rings of Uranus extend from 1.49 Ru to 1.95 Ru, which is within a region usually reserved for the plasmasphere. (The Earth's plasmasphere extends from 1 Re to roughly 6 Re).

At Uranus, the rings have a greater sweeping effect due to the extreme tilt of the axis of the magnetic field. The tilt extends the range of the rings down to about 1 Ru.

Uranus' Plasmasphere

Uranus' plasmasphere is tiny. The rings of Uranus sweep away much of the particles in the area. Particles enter the plasmasphere from the atmosphere as well as the magnetotail. Mathematical theory suggests...more
