Asteroid 2024 YR4, initially discovered on December 27, 2024, was first noted for a 3.1% chance of impacting Earth on December 22, 2032. However, as more observations have been collected, NASA has revised this probability downward to approximately 0.004%, effectively removing Earth from the list of impact concerns. ?

Recent observations by the James Webb Space Telescope (JWST) have provided new insights into the asteroid's characteristics. These observations suggest that 2024 YR4 is slightly larger and rockier than previously estimated. This data is crucial for refining its trajectory and assessing potential impact risks.

While Earth is no longer considered at significant risk, the Moon remains within the asteroid's potential impact zone. Current estimates indicate a 2% chance of collision with the Moon. Such an event would offer a unique opportunity for scientists to study the effects of asteroid impacts on the lunar surface.

Astronomers will continue to monitor 2024 YR4 using both ground-based and space-based telescopes, including the JWST, to refine its orbit and size estimates. These ongoing observations are essential for updating impact probabilities and preparing for any potential threats.
