What Happens if an Asteroid Hits the Moon? Astronomers Are Racing to Find Answers
NONE, JUL 25 – Asteroid YR4 poses a 4.3% chance of impacting the moon in 2032, potentially threatening lunar infrastructure and Earth-orbiting satellites, scientists say.
- Astronomers tracked asteroid 2024 YR4, a building-sized space rock discovered late in 2024, noting on June 3 a 4.3% chance it could impact the moon.
- The lunar impact probability peaked at 3.1% in February and varied with new observations before YR4 passed out of view, prompting planetary defense efforts.
- YR4 is estimated about 60 meters wide, and if it strikes, it could produce the largest lunar impact in 5,000 years with a bright flash visible to the naked eye.
- Dr. Paul Wiegert stated there is no danger to anyone on Earth's surface but cautioned satellites and lunar infrastructure might be at risk, urging expansion of protective shields.
- This event highlights the critical role of advanced telescopes and detection programs, as humanity depends heavily on space infrastructure and evolving planetary defense measures.
