Should 2024 YR4 enter Earth’s atmosphere, the most likely scenario is an airburst—an explosion in the air. This airburst would release energy equivalent to approximately eight megatons of TNT, more then 500 times the power of the Hiroshima atomic bomb. Though, an impact crater remains a possibility, depending on the asteroid’s precise size, according to experts.
the potential impact zone encompasses a wide swathe of the globe, including the eastern Pacific Ocean, northern South America, the Atlantic Ocean, Africa, the Arabian Peninsula, and South Asia. while the risk remains low,one expert noted,It’s a very,very rare event,
adding,This is not a crisis at this point in time. This is not the dinosaur killer.This is not the planet killer. This is at most hazardous for a city.
experts stress that it’s far too early for drastic measures like relocation.
A formal warning would be issued by the International Asteroid Warning Network (IAWN) if the risk surpasses 10 percent. This would trigger a proposal for all UN members who have territories in potentially threatened areas to start terrestrial preparedness,
according to one expert. Even in a worst-case scenario, we are not defenceless,
they emphasized, highlighting the ample time available to develop and implement mitigation strategies.
The ongoing monitoring of 2024 YR4 using the Webb telescope’s data is crucial for refining trajectory predictions and assessing the evolving risk. The situation underscores the importance of continued investment in planetary defense initiatives and international collaboration to address potential asteroid threats.
The extraordinary capabilities of the James Webb Space Telescope have unveiled unprecedented details about 2024 YR4,an asteroid classified as a “city killer.” What’s truly captivating is its ability to discern even the faintest objects in space, enabling astronomers to refine trajectory predictions.

The telescope’s revelations serve as a powerful reminder of how even celestial bodies seemingly billions of miles away can have a profound impact on Earth. As we harness such cutting-edge technology, we amplify our ability to foresee and manage these cosmic challenges effectively.
While the asteroid responsible for the dinosaur extinction was colossal, measuring about 10 kilometers in diameter, 2024 YR4 is significantly smaller yet still a formidable threat at a localized level. The real peril of 2024 YR4 lies in its rapid velocity, estimated to reach nearly 64,000 kilometers per hour upon impact—an attribute that amplifies its destructive potential, akin to an eight-megaton TNT explosion. While it isn’t a global cataclysm, its impact could devastate a specific city.This distinguishes it as a “city killer,” a term emphasizing the localized yet severe nature of the threat, unlike ancient asteroid impacts with global-scale consequences.
Current predictions suggest that while an impact might not be immediate, the asteroid’s trajectory places it in close proximity during its next flyby in 2028.The James Webb Space Telescope’s ability to track and refine these trajectory predictions is pivotal. The International Asteroid Warning Network (IAWN) issues formal warnings if the risk exceeds a 10% threshold, triggering discussions for UN members to initiate terrestrial preparedness strategies. Despite the potential threat, it’s critical to note that the risk remains low, emphasizing that drastic measures like relocation are unnecessary at this stage. This situation underscores the importance of investing in planetary defense initiatives and international collaboration to prepare for any eventualities.
The ongoing monitoring of 2024 YR4 is a testament to humanity’s resilience and ingenuity. Although the asteroid poses a potential threat, our capacity for detection, preparedness, and response has never been stronger. It’s crucial for us to continue investing in planetary defense and fostering a culture of collaboration and readiness.By doing so, we empower not only our current generation but future ones to navigate the challenges of the cosmos.
