Today is World Asteroid Day!



June 30 is globally observed as World Asteroid Day to raise and spread awareness about the impact of the asteroids on the Earth. It is a kind of movement to spread knowledge and the possible things which can be done to protect the earth from asteroids.

Asteroids are the rocky bodies that orbit around the sun. They range in size from about the size of pebbles to around 600 miles across. They are generally known as the leftover material of the Solar System. More than 1M asteroids have the potential to impact Earth and till now we have been able to discover only about one percent.

In December 2016, the United Nations General Assembly adopted a resolution A/RES/71/90 and declared 30 June to be observed as International Asteroid Day. The day marks the anniversary of the Tunguska impact over Siberia, Russian Federation, on 30 June 1908, the most harmful known asteroid-related event on Earth recorded in recent history.  A large explosion occurred near the Podkamennaya Tunguska River in Russia, on the morning of 30 June 1908. This event flattened 2,000 square kilometers (770 square miles) of the forest.

A declaration called "100X Declaration", signed by more than 22,000 private citizens, was created. It appeals to scientists and technologists to increase the asteroid discovery rate. B612 is the organization that works towards protecting the Earth from asteroid hazardous impacts.

The first Asteroid Day was observed on June 30, 2015. In 2019, the fifth Asteroid day is being observed. Different events are organized by planetariums, museums, and universities all over the globe to observe the day. 
NASA’s Earth impact monitoring system has detected an asteroid, having a diameter of 1,115 feet, approximately taller than the Eiffel Tower in France, has a chance of hitting Earth in October 2019.
