International Asteroid Day: Significance & facts about Asteroids

International Asteroid Day is all set to celebrate its sixth year on this 30th June with events across all over the globe. The purpose of Asteroid Day is to excite, engage, and educate the public about the potential and threats posed by asteroids.

How did it form?

After the release of the film ’51 Degrees North’ in 2014, which explores what might happen if an asteroid struck London, the holiday was founded. The film’s creators aimed to raise awareness about asteroids’ threat to Earth and how we may help protect ourselves. They established a foundation to accomplish this, and in 2015, they celebrated the world’s first International Asteroid Day.

Significance of International Asteroid Day

World Asteroid Day is observed globally each year from 2015 on June 30, the day on which the world’s greatest asteroid event took place in 1908 in Siberia. The Tunguska asteroid event, which occurred on June 30, 1908, in Siberia, Russian Federation, was the greatest asteroid impact in recorded history.

Since the inception of International Asteroid Day, the main motto of observing this day is to promote public awareness about the asteroid impact threat.

History of Tunguska asteroid event

On the morning of June 30, 1908, a large explosion occurred near the Podkamennaya Tunguska River in the Yeniseysk Governorate of Russia (now Krasnoyarsk Krai). The explosion, which occurred over the sparsely populated Eastern Siberian Taiga, flattened an estimated 80 million trees over a 2,150 km2 forest region, and eyewitness reports claim that at least three persons were killed. The explosion is thought to have been caused by the air burst of a stony meteoroid of about 100 metres (330 feet) in diameter.

Did you know?

There are approximately one million asteroids in orbit that could collide with the earth, yet only around 1% of them have been found by current science. The 100X Asteroid Declaration was prepared by Asteroid Day’s founders, together with a number of distinguished scientists, to counteract this. Scientists will try to increase the rate of asteroid discovery to 100,000 per year within a decade, according to the declaration.

International Asteroid Day encourages people of all ages to pick up a book and learn more about the sky above them and the galaxy that surrounds us. Observing this day is a great way to combat the lack of awareness around the issue. In the event that an asteroid hit the planet, the holiday and the events surrounding it could make a big impact in people’s ability to protect themselves.
