Origins & Early Life

Asteroid impact avoidance encompasses the methods by which near-Earth objects (NEO) on a potential collision course with Earth could be diverted, preventing destructive impact events. An impact by a sufficiently large asteroid or other NEOs would cause, depending on its impact location, massive tsunamis or multiple firestorms, and an impact winter caused by the sunlight-blocking effect of large quantities of pulverized rock dust and other debris placed into the stratosphere.

Career & Major Achievements

A collision 66 million years ago between the Earth and an object approximately 10 kilometers (6 miles) wide is thought to have produced the Chicxulub crater and triggered the Cretaceous–Paleogene extinction event that the scientific community understands to have caused the extinction of all non-avian dinosaurs. While the chances of a major collision are low in the near term, it is a near-certainty that one will happen eventually unless defensive measures are taken.

Enduring Legacy & Impact

Astronomical events—such as the Shoemaker-Levy 9 impacts on Jupiter and the 2013 Chelyabinsk meteor, along with the growing number of near-Earth objects discovered and catalogued on the Sentry Risk Table—have drawn renewed attention to such threats.

Historical Fact-Check Quiz: Asteroid impact avoidance

True or False: “The primary threat from a large asteroid impact is not just the impact itself, but also the subsequent 'impact winter' caused by debris blocking sunlight.”

Answer (TRUE ⭕): The debris placed into the stratosphere can block sunlight for extended periods, leading to a global cooling event known as an impact winter, which is a major secondary hazard.
