FAQ
Frequently Asked Questions
The leading scientific consensus is that it was caused by the atmospheric explosion of a stony meteoroid or comet fragment approximately 5-10 km above the surface.
It is the largest recorded impact-like event on Earth and serves as a key case study for understanding the frequency and effects of airbursts from near-Earth objects.
It is a proper noun borrowed from Russian, used in English to specifically refer to the geographical region and the 1908 event. It is not a general vocabulary item.
No major impact crater has been found, supporting the theory that the object disintegrated in an airburst, with only smaller fragments and microscopic evidence reaching the ground.
