It was on this day in 1908 that about 800 square miles of forest in Siberia were decimated in what was later attributed to an meteor exploding 3 to 6 miles above the Tunguska River area. As a result of the aerial explosion, no impact crater was created from what was called the Tunguska Event.
The meteor that hit Russia has been estimated top be 160–200 feet wide. The asteroid that passed by the Earth yesterday, 2024 MK, has been estimated to be 400 and 850 feet wide. We are lucky that we did not need to go through this again more than 100 years later.
The Tunguska Event is the largest impact event in recorded history. It was this event that later inspired what we celebrate today – Asteroid Day.
Happy Asteroid Day!
