International Asteroid Day 2020: History, significance and importance of this day
New Delhi | Jagran News Desk: International Asteroid Day is observed on June 30 every year to make people aware about asteroids and the possible hazards they could cause during an impact. International Asteroid Day is also observed to make aware about the importance and role played by asteroids in our solar system.
The United Nations General Assembly (UNGA) had passed the resolution 2016 and declared that June 30 will be observed at International Asteroid Day every year. It had said that International Asteroid Day will be observed “every year at the international level the anniversary of the Tunguska impact over Siberia, Russian Federation, on 30 June 1908, and to raise public awareness about the asteroid impact hazard”.
Why International Asteroid Day is observed on June 30 every year?
International Asteroid Day is observed every year to remember the Tunguska asteroid event on 30 June 1908, which is the earth’s largest asteroid impact in recorded history.
According to National Aeronautics and Space Administration (NASA), a 220-million-pound asteroid entered earth’s atmosphere at a speed of 33,500 miles per hour, generating heat of about 44,500 degrees Fahrenheit which was equal to 185 Hiroshima bombs. As per reports, the impact destroyed 2,150 square km of area.
International Asteroid Day celebrations:
Over 2,000 events were organised across the world to observe the first International Asteroid Day. However, this year the International Asteroid Day will be observed online due to the ongoing coronavirus crisis.
“Topics of discussion this year include the acceleration in the rate of our asteroid discoveries and why it is set to accelerate even faster, the imminent arrival of samples from asteroid Ryugu and Bennu, the exciting preparations for the joint US-Europe mission to binary asteroid Didymos, and much more,” said official International Asteroid Day website.
Here are some quotes about International Asteroid Day:
“The idea is to raise awareness of, not only the dangers of asteroids but also the fact that we have solutions in hand to find dangerous asteroids and do something about it.”
“A hybrid human-robot mission to investigate an asteroid affords a realistic opportunity to demonstrate new technological capabilities for future deep-space travel and to test spacecraft for long-duration spaceflight.”
“Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, but once we spread out into space and establish independent colonies, our future should be safe.”
“It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.”
“We really need an internationally agreed and coordinated strategy for the development of asteroid litigation technology and very importantly the implementation of procedures for an emergency deflection scenario.”
“Changing the asteroid's velocity changes the time when the asteroid crosses Earth's orbit. After all, just because it crosses Earth's path doesn't mean there is necessarily going to be a collision. It has to cross Earth's path when the Earth is right there.”
