Planetary Catastrophes

Planetary Catastrophes
Planetary Catastrophes Sometime in the distant past, an asteroid or comet struck Saturn's moon Mimas with nearly enough force to break the satellite into pieces, leaving a giant crater over 100 kilometers across. Another wayward asteroid or comet may have struck Earth 65 million years ago, causing the extinction of the dinosaurs. This computerized image of Mimas accentuates the crater, appearing here in relief against the darkened limb of the satellite. Alan Ames, I.M.A.G.E.S.
