The Popigai impact structure is the eroded remnant of an impact crater in northern Siberia, Russia. It is tied with the Manicouagan structure as the fourth largest verified impact structure on Earth. [1] [2] A large bolide impact created the 100-kilometre (62 mi) diameter crater approximately 35 million years ago during the late Eocene epoch ...
Asteroid Day (also known as International Asteroid Day) is an annual global event which is held on June 30, the anniversary of the Tunguska event in 1908 when a meteor air burst levelled about 2,150 km 2 (830 sq mi) of forest in Siberia, Russia. Asteroid Day was cofounded in 2014 (the year after the 2013 Chelyabinsk meteor air burst) by ...

One of the best-known recorded impacts in modern times was the Tunguska event, which occurred in Siberia, Russia, in 1908. This incident involved an explosion that was probably caused by the airburst of an asteroid or comet 5 to 10 km (3.1 to 6.2 mi) above the Earth's surface, felling an estimated 80 million trees over 2,150 km 2 (830 sq mi).
