Astronomers say an asteroid moving at 10 kps came within 75,000 miles of the Earth last week. They didn’t see it until three days after it would have hit.
The destructive force might have been comparable to an asteroid or comet that exploded over Siberia in 1908, which flattened 77 square miles (200 square km) of trees, according to the NEO.
Wouldn’t that have ruined your day…
