Hey, Space Placers!
The unseen asteroid screamed in from the Sun like an enemy fighter - never seen until it exploded with the force of 600,000 tons of TNT force - 35 times the atomic bomb dropped on Hiroshima, Japan.
Thousands of casualties, buildings damaged and one million meters of glass broken. This was the asteroid that changed our thinking about the threat posed by a space rock 65-feet across.
Previously we didn't think this size space rock posed a serious threat. WE.WERE.WRONG.
A lot has changed since then for the better.
