NASA Continues to Monitor Orbit of Near-Earth Asteroid 2024 YR4
While still an extremely low possibility, additional observations and analysis of asteroid 2024 YR4 indicate that its impact probability with Earth has increased to a 2.3% chance on Dec. 22, 2032. Ongoing observations from ground-based telescopes involved with the International Asteroid Warning Network will continue while the asteroid is still visible through April, after which it will be too faint to observe until around June 2028.
NASA’s James Webb Space Telescope will also observe the asteroid in March 2025 to better assess the asteroid’s size. Currently the asteroid is estimated to be 130-300 feet across.
As more observations of the asteroid’s orbit are obtained, its impact probability will become better known. It is possible that asteroid 2024 YR4 will be ruled out as an impact hazard, as has happened with many other objects that have previously appeared on NASA’s asteroid risk list, maintained by NASA’s Center for Near-Earth Object Studies. It is also possible its impact probability will continue to rise. The latest data will continue to be made available via NASA’s automated Sentry page.
Asteroid 2024 YR4 is a near-Earth asteroid, meaning it is an asteroid in an orbit that brings it into Earth’s region of the Solar System. 2024 YR4 is estimated to be about 130 to 300 feet (40 – 90 meters) wide and has a very small chance of Earth impact on Dec. 22, 2032.
This object is of particular interest for planetary defense for two reasons: 1) it is large enough to cause localized damage in the unlikely event that it should impact Earth, and 2) while 2024 YR4 has a very small chance of Earth impact in 2032, it has surpassed the 1% impact probability threshold to warrant formal notification of the object to other U.S. government agencies involved in planetary defense as well as to the Space Mission Planning Advisory Group and to the United Nations Office of Outer Space Affairs per the International Asteroid Warning Network’s notification charter.

Updates will also continue to be posted on NASA’s planetary defense blog.
