Asteroid Day 30th Junehttps://asteroidday.org/ Asteroid Day is a global awareness campaign where people from around the world come together to learn the dangers asteroids pose and what we can do to protect our families, communities, and future generations. The United Nations declared June 30 as Asteroid Day. The date of Asteroid Day commemorates the anniversary of the Tunguska asteroid impact over Siberia, Russian Federation, on 30 June 1908. All around the globe, regionally organised events are held on Asteroid Day. These events range from live concerts and community events, to lectures and other educational programmes, to raise public awareness of the need for increased detection and mapping of asteroids.
