Well, yesterday was Asteroid Day… It occurs every year on June 30th…
Asteroid Day (also known as International Asteroid Day) is an annual global event which is held on the anniversary of the Tunguska event in 1908, when an asteroid leveled about 2,150 square kilometres (830 sq mi) forest in Siberia. The United Nations has proclaimed it be observed globally on June 30 every year in its resolution. Asteroid Day aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations from a catastrophic event. For example, 2014 HQ124, discovered April 23, 2014, went past 1,250,000 km from Earth the same year, June 8th, only 46 days after discovery, and 2015 TB, went past at 490,000 km only 21 days after its discovery.
Asteroid Day was co-founded by Stephen Hawking, filmmaker Grigorij Richters, B612 Foundation President, Danica Remy, Apollo 9 astronaut Rusty Schweickart and Brian May, Queen guitarist and astrophysicist.
