This is a list of possibly hazardous near-Earth objects with Torino scale rankings that are non-zero or that were, at one time, non-zero. This means that they are, or were once, potentially hazardous objects with respect to Earth.

Torino scale

Potential impacts with high ratings

In March 2002, became the first asteroid with a temporarily positive rating on the Torino Scale, with about a 1 in 9,300 chance of an impact in 2049. Additional observations reduced the estimated risk to zero, and the asteroid was removed from the Sentry Risk Table in April 2002.

Most potential impacts listed on NASA's Sentry List Table or ESA's Risk List have a Torino scale rating of 0, a few each year reach a rating of 1. , only three objects ever received a rating above 1.

On December 24, 2004, asteroid 99942 Apophis was assigned a 4 on the Torino scale, the highest rating given to date, for an impact in April 2029. As observations were collected over the next three days, the calculated chance of impact first increased to as high as 2.7%, then fell back to zero. The risk of impact during later close approaches was eliminated and Apophis was removed from the Sentry Risk Table in February 2021.

In February 2006, , having a diameter around 300 metres, was assigned a Torino Scale rating of 2 due to a close encounter predicted for May 4, 2102. After additional observations allowed increasingly precise predictions, the Torino rating was lowered first to 1 in May 2006, then to 0 in October 2006, and the asteroid was removed from the Sentry Risk Table entirely in February 2008.

In late January 2025, asteroid was assigned a Torino scale rating of 3, and had a chance of impact as high as 3.1% on December 22, 2032. Astronomers responded by scheduling more observations (including the James Webb Space Telescope) as the object receded and got dimmer, to determine its orbit with more precision and thus improve the impact risk prediction. Had been confirmed to be on collision course with Earth, its Torino scale value would have been upgraded to 8. The DART mission has proven the capability of redirecting small asteroids, and currently active launch vehicles are sufficient to redirect if it had been determined necessary during 2028. However, it was downgraded to a Torino Scale rating of 0 on February 23, 2025.

Four have cumulative Palermo scale values between −2 and −3: (−2.38), (−2.69), (−2.77) and (−2.97).

, on the Risk List maintained by the Near-Earth Object Coordination Centre of the European Space Agency (ESA), one asteroid has a cumulative Palermo scale value above −2: 101955 Bennu (−1.41). Five have cumulative Palermo scale values between −2 and −3: 1950 DA (−2.13), (−2.67), 1979 XB (−2.70), (−2.73) and (−2.77). Of the 27 that have a cumulative Palermo scale value between −3 and −4, three were discovered in 2024 and three in 2025: (−3.45), (−3.51), (−3.53), (−3.74), (−3.82) and (−3.96).

List of potential impacts with non-zero peak ratings

Below is a comprehensive list of asteroids with potential impacts on Earth over the next 100 years that had been assigned peak cumulative Torino scale ratings above 0 on NASA's Sentry Risk Table.

Currently non-zero

none

Downgraded to zero This is a partial list of near-Earth asteroids that have been listed with a Torino scale rating of 1+ and been lowered to 0 or been removed from the Sentry Risk Table altogether. Most objects that reach a Torino scale of 1 have a short observation arc of less than 2 weeks and are quickly removed as the observation arc gets longer and more accurate.

2025 (diameter ) reached level 1 on 25 April 2025, due to a potential impact on September 19, 2089, at 6:43 AM (UTC) with a probability of 0.012%. NASA estimated the kinetic energy of the impact to be equivalent to , which is equivalent to 280% of Tsar Bomba or 70% of the energy released from Krakatoa's eruption. The asteroid passed around from the Moon and from Earth on September 18, 2025. According to ESA using 1-sigma values, the 2089 approach is on September 23, 2089 03:00 ± 1.5 hours at about 0.04 AU, which is four days after the virtual impactor scenario. On 29 April 2025, the probability of the 2089 impact was 0.009%. On May 1, 2025, the probability of the impact dropped to 1 in 13,000 (0.0075%) and the rating was reduced to 0. On May 17, 2025, it was removed from the risk table. The JPL SBDB using 3-sigma values, shows the close approach to be September 23, 2089 03:00 ± 9 hours at a distance of 0.036 to 0.046 AU. 2024 (diameter ) reached level 1 on 30 December 2024 and was uprated to level 3 on January 27, 2025, due to a potential impact near December 22, 2032 14:02 (UTC). Using NASA's estimates, the risk peaked at 1 in 32 (3.1%) on February 18, 2025, based on a 55-day observation arc. The high rating triggered the activation of planetary defense policies to use large telescopes not used for general NEO surveys, including the James Webb Space Telescope, to extend the time the object can be tracked as it recedes from Earth. Two days later, after additional observations progressively decreased the uncertainty, the estimated risk dropped to 1 in 370 (0.27%) and the impact hazard was lowered back to level 1. Another three days later, on February 23, 2025, the estimated risk dropped to 1 in 26,000 (0.0039%) and the rating was reduced to 0. By April 2, 2025, all three risk-lists had removed the chances of a 2032 impact. In the April 2025 solution by NASA, the nominal (most probable) distance from Earth on December 22, 2032, is with a 3-sigma uncertainty region of about ± around the nominal closest point; while in ESA's solution, the nominal distance is with a 3-sigma uncertainty region of about ±. NASA estimated the kinetic energy of the impact to be equivalent to . Later on December 22, 2032, the asteroid will have a very close encounter with the Moon, and the probability of a Moon impact is about 4%. 2023 (diameter ~300 meters) with an observation arc of 38 days showed a 1 in 29000 chance of impact on October 10, 2119, meriting a Torino scale rating of Level 1. The nominal distance from Earth on October 10, 2119, is with a 3-sigma uncertainty region of more than a billion km that wraps around the asteroids orbit.
