Here’s what you’ll learn when you read this story:A meteorite that plummeted into the roof and living room of a house in McDonough, Georgia, has now been found to be 20 million years older than Earth. Researchers who examined fragments of the broken meteorite now think that its parent body split from a monster asteroid (which formed before Earth) about 470 million years ago. The McDonough meteorite is only the size of a cherry tomato, but its trajectory and velocity could tell us more about larger impacts and prepare us to possibly thwart them. He had no idea if insurance would cover damage done by a space rock that turned out to be older than Earth itself. Watch for falling space rocks.
