The fifth annual International Asteroid Day happens on Sunday, June 30, 2019. Recognized by the United Nations, Asteroid Day marks a global opportunity to raise awareness of the threat and opportunity posed by the numerous rocky bodies zooming through space. A five-day broadcast – on asteroids and space topics – began on June 27 and is still running today. Here’s a program schedule, plus how to watch, wherever you are.

Central to Asteroid Day this year is what’s called the 100x Declaration, calling for a 100-fold increase in the detection and monitoring of asteroids. Signed to date by more than 50,000 people around the world, the Declaration resolves to “solve humanity’s greatest challenges to safeguard our families and quality of life on Earth in the future.” If you want to sign, the online Declaration is here.

This year, Asteroid Day events will focus on the role of asteroids in the formation of our solar system and advances in technology to better detect, track and analyze asteroids and review our ability to deflect a rogue asteroid headed towards Earth.

Asteroid Day is held on the anniversary of the most devastating asteroid impact in Earth’s recent history – an event that took place on June 30, 1908, known as the Tunguska explosion, when a small asteroid struck the Earth over Tunguska, Siberia. Here’s the premise of Asteroid Day, in the words of co-founder Brian May, astrophysicist, guitarist and songwriter for the band Queen:

Our goal is to dedicate one day each year to learn about asteroids, the origins of our universe, and to support the resources necessary to see, track and deflect dangerous asteroids from Earth’s orbital path. Asteroids are a natural disaster we know how to prevent.
