NASA's James Webb Space Telescope Refines Orbit of Near-Earth Asteroid 2024 YR4, Rules Out Lunar Impact in 2032
NASA's James Webb Space Telescope has provided new data on near-Earth asteroid 2024 YR4, allowing experts to refine its orbit and rule out a potential lunar impact on December 22, 2032. The asteroid is now projected to pass by the moon at a distance of 13,200 miles. This update is based on improved precision in tracking the asteroid's path rather than a change in its trajectory. Previous analyses had suggested a 4.3% chance of a lunar impact before the new observations were incorporated.
The observation team, led by the Johns Hopkins Applied Physics Laboratory, used the Webb telescope to capture additional data on asteroid 2024 YR4, which has been difficult to observe since 2025. The asteroid was first discovered in late 2024 by a NASA-funded station in Chile. Initial trajectory predictions raised concerns about a potential Earth impact, but further observations from various observatories worldwide have since determined that the asteroid poses no significant risk of impact on Earth in 2032 or beyond.
The use of Webb's unique capabilities to observe the faint asteroid has provided valuable insights into its path and eliminated the possibility of a lunar impact in 2032. With ongoing advancements in observational technology and data analysis, NASA continues to monitor near-Earth objects to ensure the safety of our planet from potential impacts.
