In January 1986, the first human-made visitor to Uranus was Voyager 2. Left is a true-color view of the planet and a false color view is right.
Some of the most interesting Voyager discoveries were from the many moons orbiting the giant gas planets. One of them is Miranda, the innermost of Uranus' large moons, is about 22,000 miles away from Voyager 2 in this photograph.
This clear-filter, narrow-angle image shows an area about 150 miles across. Two distinct terrain types are visible: a rugged, mountainous region (right) and a lower, striated terrain (left). Craters on the higher terrain show that it is older than the lower terrain. The crater in the lower part of this image is about 15 miles across.
Voyager returned these images of Neptune's rings.
