Editing Torino scale (section)

==Overview==

The Torino scale uses an integer scale from 0 to 10. A 0 indicates an object has a negligibly small chance of collision with the [[Earth]], compared with the usual "background noise" of collision events, or is too small to penetrate [[Earth's atmosphere]] intact. A 10 indicates that a collision is certain, and the impacting object is large enough to precipitate a global disaster.

An object is assigned a 0 to 10 value based on its collision probability and the [[kinetic energy]] of the possible collision.

The Torino scale is defined only for potential impacts less than 100 years in the future.

"For an object with multiple potential collisions on a set of dates, a Torino scale value should be determined for each date. It may be convenient to summarize such an object by the greatest Torino scale value within the set."<ref name=nasa>{{cite web|url=http://impact.arc.nasa.gov/torino.cfm |title=Torino Impact Scale |access-date=March 11, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070224184143/http://impact.arc.nasa.gov/torino.cfm |archive-date=February 24, 2007 }} Torino Impact Scale (NASA Ames)</ref>
