Asteroid Day is a global awareness movement where people from around the world come together to learn about asteroids and what we can do to protect our planet, our families, communities, and future generations. Asteroid Day will be held on the anniversary of the 1908 Siberian Tunguska event, the largest asteroid impact on Earth in recent history. You can now sign the 100x Declaration yourself here
