Uranus and three satellites seen by Voyager 2 - Image obtained by the Voyager 2 probe in January 1986 showing the planet Uranus accompanied by the satellites Ariel (top right), Miranda (closest to the planet) and Umbriel (bottom left). This Voyager photograph of Uranus taken in january 1986 is a composite of for images taken by the narrow angle camera. At this range, clouds and other features in the atmosphere as small as 1,370 km. could be detected by Voyager 2. Yet, no such features are visible. This view is toward the illuminated south pole of Uranus. The predominant blue color is the result of atmospheric methane, which absorbs the red wavelengths from incoming sunlight. The spot at the upper left edge of the planet's disk reulted from the removal of a network mark used in making measurments on the photograph. Three of Uranus' five known satellites are visible; Miranda (at far right, closest to the planet), Ariel (next out, at top), and Umbriel (lower left). Titania and Oberon are now outside the narrow angle camera's field of view when it centered on the planet. This color composite was made from images taken through blue, green, orange, and clear filters
