60-Meter Asteroid Could Slam the Moon in 2032, Opening a Rare Lunar Science Window

Asteroid 2024 YR4, about 60 meters wide, could strike the Moon in December 2032 with roughly a 4.3% probability, releasing energy comparable to 6.5 million tons of TNT and creating a ~1-km crater visible from Earth. The impact could trigger Moonquakes and reveal subsurface details, while lunar debris might reach Earth’s orbit and threaten satellites, prompting a debate between potential deflection (as demonstrated by NASA’s DART mission) and pursuing scientific observations of the event.

Moon could glow like Venus if 2024 YR4 hits in 2032, new simulations suggest

A new arXiv preprint reports that asteroid 2024 YR4, about 60 meters across, has a 4.3% chance of striking the Moon in 2032. Using 10,000 simulated trajectories, researchers map a ~3,000 km impact corridor just north of Tycho crater. The impact could unleash about 6.5 megatons of TNT energy, producing a Venus-bright flash (-2.5 to -3 magnitude) lasting 3–5 minutes and visible from Earth under favorable lighting, with a minority (about 2.85%) of flashes observable from our side of the Moon’s illuminated face. The event could eject up to 100 million kilograms of lunar rocks toward Earth, potentially triggering thousands of secondary flashes and “super meteor storms” over days to weeks. The findings are not yet peer‑reviewed.

NASA and Scientists Urge to Destroy Asteroid 2024 YR4 to Protect the Moon

NASA is considering destroying asteroid 2024 YR4 to prevent a potential impact on the Moon in 2032, which could cause debris that threatens satellites. Due to limited time and uncertainties in the asteroid's properties, the team suggests a preemptive demolition rather than deflection, emphasizing the need for early detection and planning. The approach aims to protect Earth's satellite infrastructure from lunar impact debris.

Scientists Urge Destroying Threatening Asteroid Pre-Impact

Scientists, including NASA researchers, are considering using nuclear devices to blow up the asteroid 2024 YR4, which has a very low chance of hitting Earth but a higher chance of impacting the Moon, as a method of planetary defense. The plan involves launching nuclear disruption missions within the next few years, though budget constraints and the asteroid's uncertain mass pose challenges.

Astronomers Investigate Potential Effects of an Asteroid Impact on the Moon

Astronomers are monitoring asteroid 2024 YR4, which initially posed a threat to Earth but now is more likely to impact the moon, potentially creating a visible impact event and lunar debris that could affect Earth’s space infrastructure. This situation highlights the expanding scope of planetary defense to include lunar impacts and the importance of advanced telescopes and impact mitigation strategies.

Understanding Asteroid Risks and Origins

Scientists determine the probability of an asteroid hitting Earth by tracking its orbit through astrometry, which involves precise observations over time to reduce uncertainty. As more data is collected, the predicted impact risk is refined, often decreasing as the orbit becomes clearer. The case of asteroid 2024 YR4 illustrates how initial impact probabilities can change significantly with additional observations, highlighting the importance of ongoing monitoring and effective communication about impact risks.

Scientists Warn of Potential Asteroid Impact Threats to Earth and Satellites

Scientists monitor and calculate the impact probability of asteroids like 2024 YR4 by tracking their orbits and reducing uncertainty through ongoing observations. The impact probability can fluctuate as more data is collected, ultimately providing a clearer assessment of collision risk, though communicating these risks effectively remains a challenge.
