Saving the world from asteroids (science video).

Asteroids represent a serious hazard to Earth, past, present, and future, but will be even more of a concern to humanity as we venture out to space beyond beyond our atmosphere’s protection.

A potentially hazardous object can be known not to be a threat to Earth for the next 100 years or more, if its orbit is reasonably well determined. Potentially hazardous asteroids with some threat of impacting Earth in the next 100 years are listed on the Sentry Risk Table. As of June 2020, only about 38 potentially hazardous asteroids are listed on the Sentry Risk Table.

We will explore what technologies and methods may be available to help protect us from asteroids.
