We are now 100 years after the impact of an asteroid of immense size. This impact is still the talk of asteroid observers and researchers. It exploded over a point in the old Siberian Desert in the northern part of Russia. The place is Tunguska.
Researchers are still finding out information about the Tunguska Blast of ’08, and it still awes people when they think about the power that had to have been unleashed by the collision of the asteroid as it collided with Earth and Earth’s atmosphere.
“It is estimated the asteroid entered Earth’s atmosphere traveling at a speed of about 33,500 miles per hour. During its quick plunge, the 220-million-pound space rock heated the air surrounding it to 44,500 degrees Fahrenheit. At 7:17 a.m. (local Siberia time), at a height of about 28,000 feet, the combination of pressure and heat caused the asteroid to fragment and annihilate itself, producing a fireball and releasing energy equivalent to about 185 Hiroshima bombs,” NASA report.
