Asteroid precnika 35 metara 3. Marta 2009. za dlaku izbegava sudar sa Zemljom

brkchey: Ajde malo razmislite, sta je 35metara za put kroz atmosferu?
Pa i veci kamencici sagorijevaju u prah mnogo prije nego dotaknu tlo...

Such an object traveling through the atmosphere at more than 40 times the speed of sound heats up to extreme temperatures forming a so-called fireball of superheated gas around it, which will eventually determine the asteroid to explode in multiple fragments at a relatively high altitude in the atmosphere. A similar air burst might have taken place at Tunguska, at an altitude of approximately 5 kilometers, blasting an air shock wave equivalent to about 20 megatonnes of TNT, which leveled an area of 200 square kilometers of forest. Imagine such an event taking place in a populated area or a city.
