Carlo Zapponi, a data visualization designer at Nokia, has created a pretty splendid visualization of the 1,042 meteorites that humans have witnessed hitting our planet since 861 AD. If you click the image above, you will see the visualization in full screen mode. And if you then click on various points along the timeline, you'll get essential data (produced by The Meteoritical Society) about each observed meteor strike. Most are clustered in the 19th and 20th centuries. The last is the terrifying rock that blasted through Siberia earlier this year.
Note: A total of 34,513 meteorites have hit our planet since 2500 BC. But the vast majority were never observed. They were only later found.
