NASA, aided by James Webb Space Telescope observations, has ruled out any lunar impact risk from asteroid 2024 YR4 in 2032, lowering the earlier 4.3% chance to zero and predicting a close approach about 13,200 miles from the Moon on December 22, 2032; the ~200-foot rock was discovered in 2024 by ATLAS, and concerns about a potential lunar collision have been put to rest.
Astronomers say the near-Earth asteroid 2024 YR4 has a 4.3% chance of striking the Moon in December 2032, potentially releasing about 8 megatons of energy and producing a naked-eye flash with magnitude around -2.5 to -3; an infrared afterglow could last hours and the impact could fling up to 100 million kilograms of lunar rocks toward Earth, sparking days-long meteor showers. The finding is based on 10,000 simulations and a preprint, with follow-up observations around the 2032 flyby recommended to better constrain the timeline and likely impact location.
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 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 captured a rare, bright flash on the Moon caused by a meteoroid impact, providing valuable data on space debris and impact frequency, which is crucial for future lunar exploration safety.
Astronomers in Ireland detected a rare, brief flash on the Moon caused by a small object, possibly linked to the Geminid meteor shower and asteroid 3200 Phaethon, highlighting ongoing lunar impacts during meteor showers.
An astronomer at Armagh Observatory captured what is believed to be the first video of a lunar impact flash in Ireland, during the Geminid meteor shower, marking a rare and significant event in astronomical observation.
Last year, a mystery object crashed into the Moon, leaving behind a double crater. Scientists initially believed it was a defunct Chinese rocket, but new evidence confirms its identity. However, the findings also reveal that the rocket likely carried an unknown payload. The object was first detected by researchers at the University of Arizona and was later identified as a Chinese rocket booster. The team observed variations in the light reflected off the rocket, indicating its identity. The rocket's unusual movement suggested the presence of another object on board. The double crater left by the impact is unique and requires two roughly equal masses. The identity of the object presumed to have created the second crater remains unknown, and it may never be disclosed unless China chooses to reveal it.
A viral video depicting an impact and explosion on the surface of the Moon has been debunked as fake. The video, originally posted on YouTube by user Diego Sinclair, was computer-generated and not an authentic event. While objects colliding with the Moon can create bright flashes of light, they are not caused by fire or combustion, as depicted in the video. Instead, the flashes are a result of the thermal glow of molten rock and hot vapors at the impact site. The video's creator admitted it was an edited video, leading to its rating as fake.
