Impact Probability and Affected Areas

Asteroid 2024 YR4's potential impact on Earth is an increasingly pressing concern for scientists and global authorities. Discovered in December 2023, this celestial body has been labeled a "city killer" due to its estimated width of 130 to 300 feet and its capacity to generate an impact force comparable to eight megatons of TNT. As a result, the asteroid poses a significant threat of destruction at the local level. NASA has assessed the probability of a collision at 3.1%, while the European Space Agency offers a slightly lower estimate of 2.8%. These figures underscore the need for enhanced monitoring and preparations as they reflect a notably higher-than-average risk for such events ().

The forewarned impact corridor of Asteroid 2024 YR4 spans vast regions including the Pacific Ocean, South America, the Atlantic Ocean, Africa, and South Asia, potentially putting millions at risk. Major cities like Mumbai, Kolkata, and Dhaka are particularly vulnerable, along with urban centers such as Bogotá, Abidjan, Lagos, and Khartoum. Given this widespread threat zone, international collaboration has intensified, with organizations such as NASA and the European Space Agency leading efforts in tracking and impact prediction. The use of advanced technology, exemplified by the scheduled James Webb Space Telescope observations in 2025, aims to refine impact assessments and potentially alter trajectory data, thus mitigating risks to these densely populated areas ().

Monitoring and Mitigation Strategies

Monitoring of asteroid 2024 YR4 involves a multi-faceted approach combining space-based and ground-based resources to ensure comprehensive observation and data collection. The James Webb Space Telescope is set to play a pivotal role in these efforts with observations planned for March 2025, significantly enhancing our understanding of the asteroid's trajectory and characteristics [source].
