A 15-meter wide meteor hit Russia yesterday creating a shock wave of energy that collapsed buildings, shattered windows, caused explosions and injured up to 1,000 people. A day
before after, a 45-meter wide asteroid, named 2012 DA14, made the closest recorded pass by the Earth by almost 17,000 miles.
To understand better the damage that an asteroid the size of a school bus can cause in a country in Lebanon, check out this cool simulator [KillerAsteroids] where you can drop Asteroid of 3 different sizes on a city of your choice. Here’s a small simulation showing Beirut before and after a small and medium asteroid hit it.
