{{Main|Exploration of Uranus}}
The exploration of [[Uranus]] has been entirely through the ''[[Voyager 2]]'' spacecraft, with no other visits currently planned. Given its [[axial tilt]] of 97.77°, with its polar regions exposed to sunlight or darkness for long periods, scientists were not sure what to expect at Uranus. The closest approach to Uranus occurred on 24 January 1986. ''Voyager 2'' studied the planet's unique atmosphere and [[magnetosphere]]. ''Voyager 2'' also examined its [[Rings of Uranus|ring system]] and the [[moons of Uranus]] including all five of the previously known moons, while discovering an additional ten previously unknown moons.

Images of Uranus proved to have a uniform appearance, with no evidence of the dramatic storms or atmospheric banding evident on Jupiter and Saturn. Great effort was required to even identify a few clouds in the images of the planet. The magnetosphere of Uranus, however, proved to be unique, being profoundly affected by the planet's unusual axial tilt. In contrast to the bland appearance of Uranus itself, striking images were obtained of the Moons of Uranus, including evidence that [[Miranda (moon)|Miranda]] had been unusually geologically active.
