Asteroid Day: Rock on with your space self!

Celebrate with a crash course on ASU’s NASA missions, meteorite collection and more

Planets get all the attention — just look at the ruckus raised when Pluto was demoted or anytime NASA announces exoplanet discoveries.

But on Friday, asteroids take center stage with their very own Asteroid Day, an annual event started in 2015 to commemorate the Tunguska event (the Tunguska event was a large explosion above the Podkamennaya Tunguska River in Siberia on June 30, 1908, that flattened nearly 800 square miles of forest; the cause of the explosion is generally thought to have been a meteor that burst midair).
