ASTEROID DAY

June 30, 2018

Today is the fourth annual International Asteroid Day.

This day is now recognized by the United Nations, and it marks a global opportunity to raise awareness of the threat of numerous rocks zooming through space.

Asteroid Day is held on the anniversary of the Tunguska explosion, when a small asteroid struck the Earth over Tunguska, Siberia on June 30, 1908. Recently, in a revised estimation, it is believed that the event released the energy equal to 3 to 5 megatons of TNT, devastating an area of forest about 800 square miles.

The Asteroid Day 48-hour live broadcast is happening now. You can stream the broadcast for free from the Asteroid Day website, Youtube channel or Twitter.
