The Torino scale is a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets. It is intended as a communication tool for astronomers and the public to assess the seriousness of collision predictions, by combining probability statistics and known kinetic damage potentials into a single ...
The Torino scale. The scale in metres is the approximate diameter of an asteroid with a typical collision velocity. The simple Torino scale was established at an IAU workshop in Torino in June 1999, in the wake of the public confusion about the impact risk of 1997 XF 11. [78]
Asteroid 2024 YR4 also rates 3 of 10 on the Torino Impact Hazard Scale, a method for astronomers to categorize and rate the threat of near-Earth objects. The scale ranges from 0 (no chance of ...
The chances that a near-Earth object, such as a comet or asteroid, could impact Earth is the subject of the Torino Scale and Palermo Scale. Near-Earth objects that are actively listed at the Sentry Risk Table or NEODyS should be individually included in this category. The generic category of "Potentially hazardous asteroids" is included merely ...
It's the first time ever that an object is officially classified as a Level 3 on the Torino scale. The only other object that was ever classified with a level higher than 1 was Apophis. Because of ...
For a complete list of minor planets in numerical order, ... First asteroid to rank greater than one on the Torino Scale (it was ranked at 2, then 4; now down to 0).
As of February 2025, it is listed on the Sentry Risk Table with the second highest cumulative Palermo scale rating of −0.92. [14] [15] 1950 DA is not assigned a Torino scale rating, because the 2880 date is over 100 years in the future. As of 2 February 2025, the odds of an Earth impact are 1 in 2,600 (0.039%).
It reached a Torino Scale rating of 2 and a Palermo scale rating of −0.25 (an impact hazard of about 56% of the background level). [3] With an observation arc of 17 years it is known that closest Earth approach will occur two days earlier on 2 May 2102 at a distance of about 5.5 million km. [1]
