Asteroid Day

Back on June 30, 1908, the biggest recorded potentially asteroid-related impact event occurred near the Stony Tunguska River in Russia. Now, we honor June 30 as International Asteroid Day, a day to raise awareness about asteroids, how they impact Earth, and what we can do to protect the planet.


To honor the day, NASA is featuring a special TV program with the Planetary Defense Coordination Office and other projects that study near-Earth objects (NEOs).


The program will feature several segments that will go over information about NEOs ­­– such as how they are found and characterized – as well as what to do in the event of a potential impact threat. Viewers can also send in questions for the broadcast via social media by using the hashtag #AskNASA in their post.


The Asteroid Day broadcast will air on NASA TV as well as NASA’s website starting at noon EDT.
