This "family portrait" of Uranus' five largest moons was compiled from images sent back Jan. 20, 1986, by the Voyager 2 spacecraft. The pictures were taken through a clear filter from distances of 5.0 million to 6.1 million kilometers (3.1 million to 3.8 million miles). In this comparison, we see the relative sizes and relativities of the satellites. From left, in order of increasing distance from the planet, they are Miranda, Ariel, Umbriel, Titania and Oberon. The two largest, Oberon and Titania, are about half the size of Earth's Moon, or roughly, 1,600 kilometers (1,000 miles) in diameter. Miranda, smallest of the five, has about one-quarter to one-third the diameter. Even in these distant views, the satellites exhibit distinct differences in appearance. On average, Oberon and Titania reflect about 20 percent of the sunlight, Umbriel about 12 percent, Ariel and Miranda about 30 percent. Ariel shows the largest contrast on its surface, with the brightest areas about 25 percent. All five satellites show only slight color variations on their surfaces, with their average color being very nearly gray. The best views of the satellites will be obtained Jan. 24, the day of closest approach. *Image Credit*: NASA |

This photo shows a near-infrared view of the giant planet Uranus with rings and some of its moons, obtained on November 19, 2002, with the ISAAC multi-mode instrument on the 8.2-m VLT ANTU telescope at the ESO Paranal Observatory (Chile). From top to bottom, the moons are Titania, Umbriel, Portia, Miranda, Puck and Ariel. The unidentified, round object to the left is a background star. *Image Credit*: ESO |

| Description |
Photographer : JPL Range : 74 million km. ( 46 million miles ) P-29313CThis Voyager photograph of Uranus 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 reseau 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. |
