Asteroid 2024 YR4 no longer a threat to Earth, but moon impact still a possibility

After months of careful observation, NASA and the European Space Agency (ESA) have confirmed that asteroid 2024 YR4 no longer poses a threat to Earth, putting to rest earlier concerns about a possible collision in 2032. The asteroid, first discovered in December 2023, initially raised alarm due to a 3% chance of impacting Earth. However, recent calculations have drastically reduced the risk, with ESA estimating the impact probability at just 0.001%, and NASA placing it at 0.0027%.

As a result, Earth is safe from asteroid 2024 YR4 for the foreseeable future. The asteroid will pass by our planet in 2032 with no threat of collision, and there is no significant risk for the next century.

However, while Earth is no longer in danger, scientists have identified a 1.7% chance that 2024 YR4 could strike the Moon on December 22, 2032. Researchers will continue to monitor the asteroid, with NASA's Webb Space Telescope set to make further observations next month to improve estimates of its size.

The asteroid, measuring between 130 feet and 300 feet (40 to 90 meters) in diameter, follows a four-year orbit around the Sun. It is expected to fade from view in the coming months.

Despite the initial concerns, NASA has highlighted the value of studying 2024 YR4 as an opportunity to improve asteroid tracking and impact prediction methods. As technology continues to evolve, scientists remain vigilant in their efforts to detect and prepare for potential space threats.

For now, Earth is safe, and astronomers will continue refining their strategies for defending against future asteroid risks.
