View of a crater triplet in the Noachis Terra region on Mars
The image shows three superimposed impact craters. The largest of them measures 45 kilometres across, the middle one approximately 34 and the smallest 28. One scenario for the formation of the crater triplet be that a meteoroid broke into at least three pieces on entering the Martian atmosphere before all three bodies successively hit the surface. However, it could also be a coincidence that three impactors hit Mars independently at almost the same position and over a somewhat greater time interval.
