| description |
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 |

| Description |
Photographer: JPL P-29504BW Range: 500,000 kilometers (300,000 miles) This full-disk view of Uranus' moon Titania in the early morning hours, a clear-filter image returned by the Voyager narrow-angle camera, shows many circular depressions-probably impact craters. Other bright spots are distinguished by radiating rays and are probably halo craters that mark relatively more recent impacts. Even more interesting are the linear troughs (right) that are probably fault canyons. The troughs break the crust in two directions, an indication of some tectonic extension of Titania's crust. These features indicate that this icy satellite has a dynamic, active interior. Titania is about 1,600 km (1,000 mi) in diameter, the resolution of this image is about 9 km (6 mi). |

| Description |
Photographer: JPL P-29509 BW Range: 500,000 kilometers (300,000 miles) This high-resolution image of Titania was made as Voyager 2 neared its closest approach to Uranus. Voyager's narrow-angle camera acquired this image through the violet and clear filters and shows details about 9 km (6 mi) in size. Titania has a diameter of about 1,600 km (1,000 MI). In addition to many scars due to impacts, Titania displays evidence of other geologic activity at some point in its history. The large trench-like feature near the terminator (day-night boundary) at middle right suggests at least one episode of tectonic activity, Another, basinlike structure near the upper right is evidence of an ancient period of heavy impact activity. The neutral gray color of Titania is characteristic of the Uranian satellites as a whole. |

1/24/86
| Description |
Photographer: JPL P-29522BW Range: 369,000 kilometers (229,000 miles) This is the highest-resolution picture of Titania returned by Voyager 2. The picture is a composite of two images taken through the clear-filter of Voyager's narrow-angle camera. The resolution of this image is 13 km (8 mi). Titania is the largest satellite of Uranus, with a diameter of little more than 1,600 km (1,000 mi). Abundant impact craters of many sizes pockmark the ancient surface. The most prominant features are fault valleys that stretch across Titania. They are up to 1,500 km (nearly 1,000 mi) long and as much as 75 km (45 mi) wide. In valleys seen at right center, the sunward-facing walls are very bright. While this is due partly to the lighting angle, the brightness also indicates the presence of a lighter material, possibly young frost deposits. An impact crater more than 200 km (125 mi) in diameter distinguishes the very bottom of the disk, the crater is cut by a younger fault valley more than 100 km (60 mi) wide. An even larger impact crater, perhaps 300 km (180 mi) across, is visible at top. |

| 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. |

| Title |
Uranus moon - Titania |
| Description |
The terminator region of Titania, one of Uranus' five large moons, was captured in this Voyager 2 image obtained in the early morning hours of Jan. 24, 1986. Voyager was about 500,000 kilometers (300,000 miles) from Titania and inbound toward closest approach. This clear-filter, narrow-angle view is along the terminator -- the line between the sunlit and darkened parts of the moon. The low-angle illumination shows the shape of the surface very clearly. Among the features visible are long linear valleys perhaps 50-100 km (30-60 mi) wide and several hundred km (or mi) long. At least two directions of faulting are visible, as are many circular impact craters attributed to cosmic debris. The resolution of this image is about 9 km (6 mi). The Voyager project is managed for NASA by the Jet Propulsion Laboratory. |
