January 1986 - Voyager 2 Flyby of Miranda

Uranus' moon Miranda is shown in a computer-assembled mosaic of images obtained Jan. 24, 1986, by the Voyager 2 spacecraft. Miranda is the innermost and smallest of the five major Uranian satellites, just 480 kilometers (about 300 miles) in diameter. Nine images were combined to obtain this full-disc, south-polar view. via NASA http://ift.tt/2jBNLIN
