The discovery of an observed fall of a Vestan meteorite has yielded a predicted age of 22 million years for the impact event that has directed so many pieces of rock from there to Earth.

This finding – the small fraction of the age of that impact vs. the age of the solar system – helps explain why such a disproportionate number of meteorites have resulted from just one parent body. There were likely eras in the past when a disproportionate number of meteorite falls would have come from other parent bodies after large impacts hitting them.

This provides some useful context for Vesta discoveries of all kinds, including, of course, those from the Dawn mission.
