What is Asteroid Day?
Every 30 June the global community observes Asteroid Day, an event endorsed by the United Nations that highlights the relevance of asteroid research and Earth‑protective measures.
Why this specific date?
The day commemorates the 2013 Chelyabinsk meteor event, which demonstrated how a relatively small space rock can cause significant damage.
