Honestly I didn’t know it was Asteroid Day till I checked in with NASA this morning. Their Twitter feed said it’s Asteroid Day, and who isn’t going to believe NASA. Other than Flat Earthers, Moon Landing Deniers, and the White House.

If you are wonder how to celebrate Asteroid Day, they have a free 24 hour feed here, https://asteroidday.org/live/ (Also on NASA TV). As of writing this it has Brian Cox with a panel talking about how the international community should handle regulating near earth objects. Also the AsteroidWatch Twitter feed is following todays events too https://twitter.com/AsteroidWatch.

Why you are checking things out,the NASA page for planetary defense is giving updates on the planned robotic mission to deflect asteroids to study them. https://www.nasa.gov/planetarydefense

And if you have some free time and a flash player you can always play Asteroids! for free in your browser. http://my.ign.com/atari/asteroids
