NASA has confirmed that asteroid 2024 YR4 will not strike the Moon in 2032. Initially, there was some uncertainty about its path, with a 4.3% chance of impacting the Moon. However, new observations from the James Webb Space Telescope have clarified its trajectory, showing it will pass at a safe distance of about 13,200 miles on December 22, 2032.
This asteroid was discovered in December 2024 by the Asteroid Terrestrial-Impact Last Alert System (ATLAS) in Chile. Early analyses raised concerns about a potential Earth impact, but those fears were quickly dismissed. The lingering worry about the Moon remained until recent observations.
The asteroid, roughly 200 feet wide—about the size of a 15-story building—could have created a substantial crater had it actually hit the Moon. Ed Lu, former astronaut and head of the B612 Foundation’s Asteroid Institute, noted that such an impact could have produced a crater over a mile wide, throwing debris into lunar orbit and possibly causing meteor showers visible from Earth.
Comparatively, a similar situation occurred with asteroid Apophis, which was discovered in 2004. Initial projections suggested a slight chance of impact. However, further observations confirmed it would miss Earth, reflecting how science evolves as new data comes in.
While some might be disappointed at the lack of a lunar spectacle, this reinforces how important continued monitoring of near-Earth objects is. According to NASA, advances in technology and techniques for asteroid observation are key in ensuring our planet remains safe from cosmic threats.
