NASA has officially confirmed that a so-called "city killer" asteroid, previously identified as a potential threat, now poses zero risk of colliding with the moon in 2032. The space agency had initially estimated a 4.3 per cent chance of a direct impact before issuing a definitive all-clear statement on Thursday.
Refined Orbital Calculations
Recent observations from the Webb Space Telescope in February have enabled scientists to significantly refine the orbit of asteroid 2024 YR4. This updated data reveals that the asteroid will safely pass by the moon at a distance of approximately 13,200 miles, equivalent to 21,200 kilometres, on December 22, 2032.
From Earth Threat to Lunar Near-Miss
Discovered towards the end of 2024, the asteroid initially appeared to present a potential hazard to Earth. However, scientists last year conclusively ruled out any collision with our planet for at least the next century. Despite this reassurance, the moon remained a possible target until the latest analysis.
The asteroid measures about 200 feet, or 60 meters, in diameter, categorising it as a "city killer" due to its capacity to cause substantial regional damage upon impact. The revised trajectory provides significant relief to the astronomical community and underscores the importance of continuous monitoring and technological advancements in space observation.
This development highlights NASA's ongoing efforts to track near-Earth objects and mitigate potential risks, leveraging cutting-edge tools like the Webb Space Telescope to enhance predictive accuracy and ensure planetary safety.
