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 ...
2024 YR 4 is an asteroid that is classified as an Apollo-type (Earth-crossing) near-Earth object, with an estimated diameter of 40 to 90 metres (130 to 300 ft).As of 21 February 2025, it has a rating of 1 on the Torino scale, with a 1-in-280 (0.36%) chance of impacting Earth on 22 December 2032, [7] and a rating of −1.11 on the Palermo scale, corresponding to an impact hazard 7.8% of the ...
First asteroid to rank greater than zero on the impact-risk Torino Scale (it was ranked 1; now at 0) 1998 KY 26: 0.030: June 2, 1998: Approached within 800,000 km of Earth 2002 AA 29: 0.1: January 9, 2002: Unusual Earth-associated orbit 2004 FH: 0.030: March 15, 2004: Discovered before it approached within 43,000 km of Earth on March 18, 2004 ...
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]

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%).
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 ...
Richard "Rick" P. Binzel (born 1958) is an American astronomer and professor of planetary sciences at the Massachusetts Institute of Technology (MIT). He is a discoverer of minor planets, photometrist and the inventor of the Torino Scale, a method for categorizing the impact hazard associated with near-Earth objects such as asteroids and comets.
