The goal of International Asteroid Day is to educate people around the world about asteroids. The day also aims to inform people about the possible catastrophic results of asteroid impacts on the planet. International Asteroid Day is celebrated worldwide by all member countries of the United Nations.

This day calls on global governments to create strategies to manage a calamity similar to the Tunguska event in the future.

World Asteroid Day 2023: History

It was in 2014 when World Asteroid Day began. The intention then was to inform the population about possible asteroid threats to Earth.

In 2013, a massive event occurred, the Chelyabinsk meteorite. The event promoted the concept of International Asteroid Day. The following year, a team of notable dignitaries, including Apollo 9 astronaut Rusty Schweickart, physicist Stephen Hawking, B612 Foundation president Danica Remy, filmmaker Grigorij Richters, and astrophysicist Brian May, initiated the idea of ​​the International Day of Asteroids.

The United Nations officially endorsed June 30 as Asteroid Day through a resolution in 2016.
