Asteroid 2024 YR4: NASA Updates Moon Impact Odds for 2032
Table of Contents
new data from the James Webb Space Telescope (JWST) has refined NASA’s projections for NASA Asteroid 2024 YR4, revealing a slight increase in the probability of a lunar impact in 2032.While the Earth is no longer at risk, the chance of this “city-killer” asteroid hitting the moon has risen to 4.3% [[3]].
Revised Lunar Impact Probability
The initial detection of Asteroid 2024 YR4 occurred on December 27, 2024. early calculations suggested a potential, albeit small, risk of earth impact. Though, subsequent observations have all but eliminated that possibility. Now,the focus has shifted to the potential for a lunar collision.
The updated probability stems from enhanced data gathered by the JWST.A team led by Andy Rivkin from Johns Hopkins Applied Physics Laboratory used the telescope’s near-infrared camera to refine the asteroid’s positional predictions for December 22, 2032, increasing accuracy by 20%. According to NASA, adjustments to collision probabilities are expected as new data becomes available.

asteroid 2024 YR4: Key Details
Asteroid 2024 YR4 is estimated to measure between 53 and 67 meters in length, comparable to a 10-story building. While this size could cause notable damage upon impact, astronomer Pawan Kumar, a former researcher at the Indian Institute of Astrophysics, assures that a lunar collision is “not something to worry about.” NASA also confirms that such an impact would not alter the moon’s orbit.
Initially,the probability of Asteroid 2024 YR4 colliding with Earth exceeded 1%,a historic first. This risk briefly increased to 3.1% in February 2025 before further observations drastically reduced it. By February 24, 2025, NASA announced that the collision risk had plummeted to 0.004%, confirming a safe passage in 2032.

Planetary Defense Training
Although no longer considered a threat, Asteroid 2024 YR4 presents a valuable opportunity for planetary defense training. Scientists are using this event as a real-world simulation to practice emergency response protocols, from initial detection and risk assessment to public communication. According to Kumar, “2024 YR4 is an asteroid that is very suitable for planetary defense efforts.”
The asteroid has been too faint for observation since mid-april 2025.However, scientists anticipate its reappearance in 2028, allowing for further study of its shape and composition. Data collected from telescopes in Chile and Hawaii suggest that asteroids moving into Earth’s orbit originate from the main asteroid belt between Mars and Jupiter.
| Date | Event | Collision Probability |
|---|---|---|
| December 27, 2024 | Initial Detection | >1% (Earth Impact) |
| February 2025 | Risk Increase | 3.1% (Earth Impact) |
| February 24, 2025 | Risk Reduction | 0.004% (Earth Impact) |
| June 10, 2025 | JWST Update | 4.3% (Moon Impact) |
Future observations
While the immediate threat from Asteroid 2024 YR4 has subsided, the scientific community remains vigilant. The planned observations in 2028 will provide crucial data to better understand the characteristics and origins of near-Earth asteroids. This ongoing research is essential for improving our ability to detect and respond to potential future threats.
Evergreen Insights: Background,Context,Historical Trends
The study of near-Earth objects (NEOs) is a critical component of planetary defense. NASA and other space agencies continuously monitor the skies for asteroids and comets that could potentially pose a threat to Earth. this involves not only detecting these objects but also accurately predicting their orbits and assessing their composition. The data gathered from events like the close approach of Asteroid 2024 YR4 helps refine our models and improve our response capabilities.
