Asteroid Day is June 30, marking the anniversary of a massive asteroid impact
Scientists have signed a declaration calling for increased monitoring of near-Earth objects
The threat of deadly asteroids hitting our planet is real, according to Asteroid Day, an organization hoping to stop a future catastrophe.
Scientists worldwide are observing Asteroid Day on Thursday, June 30.
The day falls on the anniversary of the Tunguska event, the largest asteroid impact yet to be witnessed. In 1908, a powerful asteroid struck the Podkamennaya Tunguska River in a remote Siberian forest in Russia.
The asteroid’s collision was so powerful that people more than 40 miles away were thrown from their porches and chairs by the sheer force of the impact, according to NASA.
