The ten-ton meteor came unannounced, hitting Russia at roughly 33,000 mph. There are about 950 people injured, two adults are in intensive care and more than 80 children were hurt. [Sky News]
Meteors are rock fragments that have broken free from asteroids or comets. They usually burn up in our atmosphere but some do hit. Meteors like the one that hit Russia happen 5 to 10 times a year.
The largest known meteorite strike in recent times was the “Tunguska event” that hit Russia in 1908 but no one was hurt. [coventry telegraph]
At the current time, there is no serious effort, only discussions, on how to stop them from hitting highly-populated areas.
