The '''Torino scale''' is a method for categorizing the [[Impact event|impact]] hazard associated with [[near-Earth object]]s (NEOs) such as [[asteroid]]s and [[comet]]s. It is intended as a communication tool for [[astronomer]]s and the public to assess the seriousness of collision predictions, by combining probability statistics and known kinetic damage potentials into a single threat value. The [[Palermo scale]] is a similar, but more complex scale.

Near-Earth objects with a Torino scale of 1 are discovered several times a year, and may last a few weeks until they have a longer [[observation arc]] that eliminates any possibility of a collision. The only objects on the Torino scale that have ever ranked higher are asteroids [[99942 Apophis]], which had a rating of 4 for four days in late 2004, the highest recorded rating; {{mpl|(144898) 2004 VD|17}}, with a historical rating of 2 from February to May 2006; and {{mpl|2024 YR|4}}, with a rating of 3 from January 27, 2025 to February 20, 2025.<ref name="Sentry2024YR4">{{Cite web |url=https://cneos.jpl.nasa.gov/sentry/details.html#?des=2024%20YR4 |title=Sentry: 2024 YR4 |work=Sentry: Earth Impact Monitoring |publisher=NASA |access-date=February 13, 2025 |url-status=live |archive-url=https://web.archive.org/web/20250201124938/https://cneos.jpl.nasa.gov/sentry/details.html#?des=2024%20YR4 |archive-date=February 1, 2025 }}</ref>
