Just in case anyone hasn’t seen the news in the last four days, a 56ft-wide asteroid weighing around 10,000 tons and travelling at 40,000 miles per hour entered the Earth’s atmosphere over Russia on February 15th. (At which point it became a meteor, not an asteroid, I’ve learned.)
It disintegrated under the force of atmospheric pressure nine miles over the city of Chelyabinsk, causing a shockwave that shattered windows across the city and injured 1200 people.
The key lesson in all this? Space is very big, and IT IS TRYING TO KILL US.
