Summary

A summary of the key points of this story verified across multiple sources.

NASA and the European Space Agency have confirmed that asteroid 2024 YR4 poses no significant threat to Earth. Initially assessed at a 3% chance of impacting in 2032, new observations have lowered this risk to 0.0027% for NASA and 0.001% for ESA, ruling out any potential collisions with Earth for at least the next century. This asteroid, first detected in December, measures between 130 and 300 feet across and orbits the sun every four years. While Earth is now safe, there remains a 1.7% chance of it impacting the moon in 2032. Observations will continue to refine tracking methods for future threats.
