Asteroid Impact: How Close Have We Come to Catastrophe


Asteroid impacts pose a significant threat to Earth, with the potential for catastrophic consequences.

Historic Near Misses

Throughout history, Earth has experienced numerous close encounters with asteroids, some of which came uncomfortably close to collision.

Tunguska Event

The Tunguska event in 1908 involved the explosion of a small asteroid or comet over Siberia, flattening trees over an area of 2,000 square kilometers.

Chelyabinsk Meteor

The Chelyabinsk meteor exploded over Russia, causing widespread damage and injuries, highlighting the potential danger of asteroid impacts.


NASA and other space agencies actively monitor Near-Earth Objects, cataloging potentially hazardous asteroids and comets.

Impact Probability

Scientists use mathematical models to assess the probability of asteroid impacts, providing early warning systems for potential threats.

Planetary Defense

Various strategies have been proposed for deflecting or mitigating the impact of asteroids, including spacecraft missions and asteroid redirection techniques.

International Cooperation

Addressing the threat of asteroid impacts requires global cooperation in detection, tracking, and mitigation efforts.

Public Awareness

Raising public awareness about the threat of asteroid impacts is crucial for mobilizing support for planetary defense initiatives.
