The
Tunguska event is considered to be the largest asteroid impact on Earth in recorded history.
"We are currently aware of less than 1% of objects comparable to the one that impacted at
Tunguska, and nobody knows when the next big one will hit.
The last time anything like the Chelyabinsk event took place was on June 30, 1908, in the area of the
Tunguska River in eastern Siberia.
He was interviewed for a Discovery Channel documentary about the
Tunguska event of 1908.
Most people with an interest in astronomy will know of the
Tunguska explosion which occurred over Siberia in 1908.
The asteroid that exploded over Russia last month was the largest object to hit Earth's atmosphere since the 1908
Tunguska event when an asteroid or comet exploded over Siberia, leveling 80 million trees over more than 830 sq miles (2,150 sq km).
At about 17 meters (55 feet) wide, this meteor is alarmingly small by cosmic standards, described by NASA scientists as a “tiny asteroid.” However it is the largest reported meteor since 1908, when an estimated 100-meter (330-foot) meteor - the largest in recorded history - exploded near the
Tunguska River in what is now Krasnoyarsk Krai, Russia.
NASA said the Russian fireball was the largest reported since 1908, when a meteor hit
Tunguska, Siberia, and flattened an estimated 80 million trees.
Computer simulations reveal that if asteroid 2012 DA 14, were to crash onto our planet, the impact will be as hard as the
Tunguska blast, which in 1908 knocked down trees over an area of 2,150sq km (830sq miles) in Siberia.
