NASA updates risk of asteroid 2024 YR4 with 4% chance of impact on the Moon in December 2032

NASA released a recent update on asteroid 2024 YR4, an object close to Terra monitored since its discovery in December 2024. Accumulated Observações indicates a 4.3% probability of collision with Lua on December 22, 2032. The space agency intensified monitoring and activated planetary defense protocols to follow the trajectory.

The asteroid has an estimated diameter of between 53 and 67 meters, a size comparable to a ten-story building. Embora the risk of impact with Terra was eliminated after refinements in the calculations, the lunar possibility required adjustments in surveillance procedures. Especialistas maintain continuous observations with ground-based and space-based telescopes.

Data from Telescópio Espacial James Webb contributed to greater accuracy in size and orbit estimates. The update reinforces the importance of the internationally coordinated planetary defense system.

• The asteroid follows a trajectory that brings it closer to the Terra-Moon system in 2032.
• Current probability of lunar impact remains around 4.3%.
• No significant risks to Terra were identified in the most recent projections.

Characteristics of asteroid 2024 YR4

Asteroid 2024 YR4 belongs to the Apollo group, with an orbit that crosses that of Terra. Sua probable composition includes rocky material typical of objects near the planet. Observações initially estimated diameter between 40 and 90 meters, but refinements reduced this range.
