The day is aimed at creating awareness around near-earth objects (NEOs), which could pose a 'potentially catastrophic' threat to our planet someday.
Asteroids are a lot more than objects of scientific curiosity. Past encounters have warned us that asteroid impacts leave a mark.
Near-Earth objects (NEOs), which comprise asteroids or comets, pose catastrophic threat to Earth as their orbits bring them close to our planet. In 2016, the United Nations officially designated Asteroid Day as the international day of awareness and education about the asteroid impact hazard.
