A bright fireball over Tokyo explodes with the force of 165 tons of TNT - CNET

A space rock reportedly causes a sonic boom as it crashes into our atmosphere over Japan.

The IMO estimates the space rock could've been around 5 feet (1.6 meters) in diameter with a mass of around 1.8 tons (1.6 metric tons).

Fireballs are common occurrences, though one large enough to generate a sonic boom is a rarer event, especially when it passes over one of the largest cities in the world
