JWST observations show asteroid 2024 YR4 will pass about 14,229 miles (22,900 km) from the Moon, with a margin of error of ±497 miles, effectively ruling out a lunar impact and easing previous fears of a Moon collision; the measurements also demonstrate Webb’s growing role in planetary defense by tracking a tiny, fast-moving asteroid and refining its orbit for future risk assessment.
A ~60-meter asteroid named 2024 YR4 could strike the Moon on December 22, 2032, with about a 4% probability, potentially creating a 1-kilometer crater and a moonquake of magnitude 5.0–5.1, offering a rare scientific 'natural experiment' as observers track optical, thermal, and seismic signals—while fallout debris could reach Earth and affect satellites.
A study estimates that if asteroid 2024 YR4 hits the Moon in 2032, it could produce a bright Moon flash (magnitude −3 to −5), carve ~1 km crater, and emit an infrared glow for hours, along with a Moonquake. About 108 kg of lunar debris might reach Earth as meteors, offering a rare scientific observing opportunity. The event has a ~3.8% probability, with potential observations starting around 2028 and best viewing from the Pacific region and Mauna Kea.
A 60-meter asteroid (2024 YR4) has about a 4% chance to strike the Moon on December 22, 2032. If it hits, it could form a ~1 km crater with a 100 m molten pool, trigger a magnitude-5.0 “moonquake,” vaporize rock, and loft up to 400 kg of debris that could reach Earth, potentially posing risks to satellites and even ground hazards. Yet scientists see this as a rare, invaluable chance to study lunar geology, interior structure, and crater formation in real time using telescopes and space assets, while some agencies consider deflection to prevent the impact.

Astronomers tested Earth's planetary defense system with asteroid 2024 YR4, which reached a Torino scale rating of 3.1% impact risk, prompting international response and detailed observation, ultimately reducing the threat level and demonstrating the effectiveness of current asteroid warning and tracking systems.
NASA has detected asteroid 2024 YR4, which could potentially collide with the Moon, offering a rare scientific opportunity to study impact effects and test planetary defense strategies, though it poses no threat to Earth.
NASA has identified a 4.3% chance that asteroid 2024 YR4, a 'city killer' about 200 feet wide, could collide with the Moon on December 22, 2032. While it poses no direct threat to Earth, a lunar impact could create a large crater and send debris toward Earth, potentially affecting satellites and creating spectacular lunar displays. Ongoing observations aim to refine the asteroid's trajectory and assess the risk, highlighting the importance of planetary defense.
A rare asteroid, 2024 YR4, has a 4.3% chance of colliding with the Moon in 2032, which could create a spectacular impact, produce lunar meteorites, and pose risks to satellites due to ejected debris, prompting planetary defense considerations.
Asteroid 2024 YR4, with a 4% chance of hitting the moon in December 2032, was only detected late due to a blind spot near the sun; ESA's upcoming NEOMIR space telescope aims to improve early detection of such objects, especially from sunward directions, and will help clarify the asteroid's future trajectory, including the potential lunar impact.
NASA's James Webb Space Telescope's final observation of asteroid 2024 YR4 has slightly increased its estimated chance of hitting the Moon from 3.8% to 4.3%, but it remains no threat to Earth. The data improved the prediction of its future path, and further observations are planned for 2028 when the asteroid returns to the inner solar system.
The James Webb Space Telescope has refined the trajectory of asteroid 2024 YR4, revealing a 4.3% chance it will hit the moon in 2032, up from 3.8%, while confirming no impact risk to Earth in the foreseeable future.
