In 1908, the Tunguska Event occurred.
It was the largest impact event on Earth in human recorded history, resulting in a massive explosion over Eastern Siberia. The event occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai) in Russia. The explosion over the sparsely populated Eastern Siberian Taiga flattened an estimated 80 million trees over an area of 830 square miles of forest, and eyewitness reports suggest that at least three people may have died in the event.
The explosion is generally attributed to the airburst of a meteoroid of about 328 feet in size. There was no impact crater since the object is thought to have disintegrated at an altitude of 3 to 6 miles above the surface.
In commemoration of the event, June 30th is observed as International Asteroid Day, a day that aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations from a catastrophic event.
Asteroid Day was co-founded by Stephen Hawking, filmmaker Grigorij Richters, B612 Foundation President, Danica Remy, Apollo 9 astronaut Rusty Schweickart and Brian May, Queen guitarist and astrophysicist. The declaration was co-signed by over 200 astronauts, scientists, technologists and artists, including Richard Dawkins, Bill Nye, Peter Gabriel, Jim Lovell, Apollo 11 astronaut Michael Collins, Alexei Leonov, Bill Anders, Kip Thorne, Lord Martin Rees, Chris Hadfield, Rusty Schweickart, and Brian Cox.
