Uranus

This ice giant has an unusual lopsided magnetic field due to a dramatic tilt of its axis that places its north and south poles where most other planets have their equator.

Atmospheric Composition
Uranus' atmosphere is primarily composed of Hydrogen with some Helium.

Miranda
Miranda is one of the smallest objects in the Sol System known to be in hydrostatic equilibrium. Its extreme and varied topography includes the Verona Rupes, which features the tallest cliff in the system.

Ariel
The surface of this moon is crisscrossed by an extensive network of scarps, canyons and ridges. Scientists speculate some of these canyons were carved out by liquid ammonia, methane or carbon monoxide.

Umbriel
This moon's name has its roots in the Latin word "umbra", which means shadow. An appropriate reference considering Umbriel is the darkest of all Uranian moons.

Titania
Titania is Uranus' largest moon. Enormous canyons and scarps cut through its surface. Scientists believe they were created after an interior expansion occurred during the moon's evolution.

Oberon
Uranus' second largest moon was named after a mythical faery king from a famous 16th century play. Its surface is covered in impact craters and appears red in color due to space weathering.
