Core Viewpoint - The European Space Agency (ESA) has confirmed a 4% probability of the near-Earth asteroid 2024 YR4 impacting the Moon in December 2032, while it poses no direct threat to Earth [1]. Group 1: Asteroid Observation - 2024 YR4 is an approximately 80-meter diameter asteroid discovered at the end of 2024 [1]. - Early monitoring raised concerns about potential Earth impact due to data uncertainty, but ESA has ruled out this risk, indicating the probability of an Earth impact is nearly zero [1]. Group 2: Potential Impact Effects - If 2024 YR4 were to collide with the Moon, it could create a crater about 1 kilometer in diameter and eject debris into the lunar space, which may pose some risk to orbiting spacecraft and satellites [1]. Group 3: Future Monitoring - ESA stated that no intervention measures are currently necessary and will continue to collaborate with international agencies to track the asteroid's orbital changes, with the next critical observation opportunity expected in 2028 [1].
