On today’s date 113 years ago, the largest asteroid impact in recorded history struck on a warm summer morning in Siberia, Russia. We observe Asteroid Day each year on June 30, on the anniversary of what’s now known as the Tunguska explosion. This explosion flattened roughly 80 million trees over an area of 830 square miles in a remote part of Siberia. It was so remote that it took scientists almost ten years to visit the site.
