This is a mosaic of Uranus' moon Miranda made from images acquired by NASA's Voyager 2 on Jan. 25, 1986. Color added as an approximation.
The ~20km-high Verona Rupes cliff can be seen at lower left.
I used about 8 images from Voyager 2 to assemble this. (One was a lower-res wide-angle shot to fill in a missing section near Verona Rupes.) Because the spacecraft was moving between shots (>19 km/sec!) I had to do some fudging to get the pieces to line up. But yes, Miranda really is that messed up.
Miranda's dimensions are 480 x 468.4 x 465.8 km. It orbits Uranus once every 34 hours.
