    To raise awareness of asteroids and the important roles they have played in the evolution of the solar system and throughout Earth’s history, June 30 is designated annually as Asteroid Day. The date commemorates Earth’s largest asteroid impact in recorded history, the Siberia Tunguska event, which leveled trees across 770 square miles, more than three times the area of Tucson, in 1908.

    Currently, the UA leads the OSIRIS-REx mission, an $800 million NASA mission that will bring back a sample from the asteroid Bennu. The UA also has the most internationally active program to identify and track Near-Earth Objects (NEOs). More than half of all known near-Earth asteroids and comets have been discovered by the UA.
