Abu Dhabi, UAE – A newly discovered asteroid, designated '2024 YR24,' has been identified as having a significant chance of colliding with Earth, according to experts from the International Astronomy Centre (IAC) in Abu Dhabi. The asteroid, first observed on December 27, 2024, could pose a "potential danger" when it passes by the planet in 2032.
Discovery and Characteristics of the Asteroid
The asteroid, detected using the Atlas system telescopes, has an estimated size ranging from 40 meters to 100 meters in diameter. To put this into perspective, at its smallest, the asteroid would measure about twice the length of a cricket pitch. At its largest, it could span the size of a football field. The IAC has highlighted the asteroid's size and trajectory as reasons for heightened concern about its potential impact.
Collision Probability and Torino Scale Rating
Asteroid 2024 YR24 has been placed on the Torino scale, which is used to assess the risk posed by asteroids that might collide with Earth. With a probability of 1.2%, the asteroid has received the highest level of classification on the scale, surpassing the well-known asteroid Apophis, which was previously thought to have a potential impact but has been ruled out.
In December 2024, the asteroid passed Earth at a distance of 829,000 kilometers without posing any immediate risk. While its 2028 passage will also not pose a danger, its third approach in December 2032 raises alarms, as it could bring it significantly closer to Earth.
Potential Impact Zone and Consequences
The asteroid is expected to come within 106,000 kilometers of Earth on December 22, 2032, with an error margin of 1.6 million kilometers. If the asteroid were to strike Earth, its impact could affect a narrow strip of land stretching from Central America, across parts of South America, through the Atlantic Ocean, parts of Africa, and possibly reach India.
The potential damage from such an impact would likely be severe but localized. Experts have drawn parallels to the 1908 Tunguska event in Siberia, where a meteorite explosion caused the destruction of around 2,000 square kilometers of forest and the uprooting of over 80 million trees. The energy released by that explosion was estimated to be equivalent to a 10-15 megaton TNT blast.
The Torino Scale and Risk Assessment
The Torino scale classifies asteroids based on the likelihood of a collision and the severity of its potential effects. A rating of 0 represents no risk, while a rating of 10 indicates a catastrophic event. The 1.2% risk posed by asteroid 2024 YR24 places it in a moderate level of concern, although it is still far from being certain.
Monitoring and Future Observations
Due to the asteroid's low brightness, it remains challenging for telescopes to observe it accurately. However, experts are urging observatories to prioritize the monitoring of 2024 YR24 in the coming years. The situation will become clearer in 2028 when astronomers will have a better opportunity to observe and analyze its path, offering more accurate predictions and potential mitigation strategies.
Despite the uncertainty surrounding its trajectory, the discovery of asteroid 2024 YR24 serves as a reminder of the importance of monitoring near-Earth objects (NEOs) and preparing for potential risks from space.
