Is the Earth Targeted for an Impact?

Not that the experts know of! None of the asteroids or comets discovered so far is on a collision course with Earth. However, they can't speak for those that are not yet discovered. In principle, one of those could hit any time, but statistically the chances are very small.




Torino Scale

The Torino Scale is a "Richter Scale" for categorizing the Earth impact hazard associated with newly discovered asteroids and comets. It is intended to serve as a communication tool for astronomers and the public to assess the seriousness of predictions of close encounters by asteroids and comets during the 21st century.
