Introduction

Let's celebrate International Asteroid Day on June 30 to recognize the importance of asteroids and the need to protect our planet from potential impacts! This day was created in 2014 to mark the anniversary of Earth's largest asteroid impact, which occurred in 1908 near Tunguska, Siberia. Although this event caused significant destruction, it also highlighted the need for continued research and education about asteroids so that we can better understand their behaviour and use them to our benefit. Join us in celebrating this important day with activities that explore outer space!
