Since 2500BC, over 35,000 meteorites are known to have hit the Earth -- but just 1107 have actually been seen falling. This visualisation shows how they pockmarked our planet over time.
Created by Carlo Zapponi, the animated visualisation is based on data from the Nomenclature Committee of the Meteoritical Society. It's quite fun to watch the animation, as the meteorites fall onto the graph, one at a time. [Bolid.es via Flowing Data]
