Asteroid 2024 YR4: Moon Impact Odds Rise, Earth Still Safe
Table of Contents
Asteroid 2024 YR4, once considered a potential threat to Earth, is now assessed to have a 4.3% chance of impacting the Moon in 2032, according to recent updates from NASA. While this represents a slight increase from previous estimates, the space agency confirms that Earth is not at significant risk from this celestial object.
The asteroid,discovered in late 2024 by the Asteroid Terrestrial-impact Last alert System (ATLAS),initially sparked concern due to its size and potential trajectory. However, further analysis has refined its projected path, shifting the focus to a possible lunar collision. The updated risk assessment comes after new data was gathered from the James Webb Space telescope and ground-based observatories.
Revised Lunar Impact Probability
NASA’s Center for Near Earth Object Studies (CNEOS) has been closely monitoring Asteroid 2024 YR4 since its discovery. The latest data indicates a slightly elevated probability of a lunar impact in December 2032.
Did You Know? โฆ
The James webb Space Telescope’s observations improved the understanding of the asteroid’s position in 2032 by nearly 20%, leading to the updated impact probability.
According to a NASA blog post, the improved data refined the projected location of the asteroid, resulting in the adjustment from a 3.8% to a 4.3% chance of hitting the Moon. Even in the event of an impact, scientists believe it would not significantly alter the Moon’s orbit. The European Space Agency (ESA) also tracks near-Earth objects and collaborates with NASA on planetary defense efforts ESA.
Current Location and Future Observations
Currently,Asteroid 2024 YR4 is too distant for telescopic observation. NASA plans to conduct further observations in 2028, when the asteroid’s orbit brings it closer to Earth again. These future observations will help to further refine the impact probability and trajectory predictions.
Pro Tip: โฆ
The probability of impact is subject to change as new data becomes available. Continuous monitoring and analysis are crucial for accurate risk assessment.
An international team,led by Dr. andy Rivkin of the Johns Hopkins University Applied Physics Laboratory, conducted observations of the asteroid in May using the james Webb Space Telescope’s near-infrared camera.
Earth impact Risk Dismissed
Initial concerns about a potential Earth impact from Asteroid 2024 YR4 have been allayed. NASA has concluded that the asteroid does not pose a significant threat to our planet in 2032 or beyond. When first identified, its estimated size of 40 to 90 meters led some to label it a “city destroyer,” but subsequent analysis has reduced the risk assessment.

The Center for near Earth Object Studies (CNEOS) uses refined models to predict the orbits of near-Earth objects. These models incorporate data from various telescopes and observatories around the world CNEOS.

Understanding Near-Earth Objects (NEOs)
Near-Earth Objects (NEOs) are asteroids and comets whose orbits bring them close to Earth’s orbit. NASA and other space agencies continuously monitor NEOs to assess any potential impact risks. The study of NEOs provides valuable insights into the formation of the solar system and the potential hazards these objects pose to our planet. Planetary defense strategies include detection, tracking, and potential deflection techniques to mitigate the risk of an impact event.
