Asteroid impact avoidance. Kinetic impactors such as the one used by the Double Asteroid Redirection Test – its impact with the asteroid moon Dimorphos photographed above – are one of many methods designed to alter the trajectory of an asteroid to prevent its potential collision with Earth. Damage caused by the Tunguska event.
Asteroid impact avoidance comprises the methods by which near-Earth objects (NEO) on a potential collision course with Earth could be diverted away, 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 ...

Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
Impact event. Damage to trees caused by the Tunguska event. The object, just 50–80 metres (150–240 feet) across, exploded 6–10 km (4–6 miles) above the surface, shattering windows hundreds of km away. An impact event is a collision between astronomical objects causing measurable effects. [1]
Asteroid impact prediction warns about asteroids hitting Earth, and when and where they will hit the Earth. Most asteroids will not hit Earth. Asteroid impact prediction works by finding the ones that will hit Earth. It finds asteroids that might hit Earth in the future. This works well for big asteroids as they can be seen easily from a long ...
