Back in 1908, some mysterious object caused an explosion in Siberia that flattened trees for hundreds of kilometers. The exact nature of the object that caused the explosion is still being worked out. Was it an asteroid that struck the ground? A comet that exploded in mid-air? A new theory proposes that it might have been a large object that just skipped off the Earth's atmosphere, and it's still orbiting the Sun. An iron object passing within 10 km of the surface could do this.
