This picture was taken 9.1 million kilometers from the planet and shows a featureless surface.

Closest approach took place on 24th January 1986 and the planet was found to have a magnetosphere highly inclined to the planets spin axis and a methane atmosphere

Voyager also imaged the three main moons of Uranus - Oberon, Titania and Umbriel
