About

Asteroid Day is a global awareness campaign created to learn about asteroids and raise awareness of the impact hazard they may pose, and what we can do to protect our planet from potential asteroid impacts. Asteroid Day is held each year on the anniversary of the largest impact in recent history, the 1908 Tunguska event in Siberia. At 131 feet across, it devastated an unpopulated area about the size of a major city -- and yet is still considered a relatively small asteroid.

If a smaller asteroid could cause that much destruction, then what about the other asteroids that we have been able to identify in our solar system? What would happen if a larger asteroid entered into the path of Earth's orbit -- would there be a way to stop it? Space is a large place; what if we haven't even spotted all the asteroids that could pose a problem in the future? It's these questions that prompted Dr. Brian May, Danica Remy (COO of B612), Grigorij Richters and Rusty Schweickart to create Asteroid Day.

Asteroid Day consists of events worldwide, ranging from lectures, educational programs, and broader community events to television programming and live concerts. The goal is to spread the word about for the need for increased awareness of asteroids.

Part of the Asteroid Day movement is The 100x Asteroid Declaration, calling for increased detection and tracking of asteroids. It has been signed by hundreds of astronauts, scientists, artists, and leaders in business and technology as well as thousands of private citizens.

Right now, more than 1 million asteroids have the potential to impact Earth and, even with our advanced telescopes and technology, it's believed that only amounts to 1% of the asteroids out there.
