Asteroid 2024 YR4: Earth Impact Risk Diminishes, Lunar Collision probability Rises

A recently discovered asteroid, designated 2024 YR4, initially sparked concerns about a potential impact with Earth, but the risk has significantly decreased. Current data suggests a growing possibility, however, that the asteroid could collide with the Moon within the next seven years.

The near-Earth asteroid was first detected on December 27, 2024, by the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope station in Chile. Initial trajectory calculations indicated approximately a 1% chance of impact with Earth on December 22, 2023. This quickly escalated to 3.1%, briefly earning 2024 YR4 the alarming moniker of “city-killing asteroid” in media reports.

from Earth Threat to Lunar Possibility

As more observations were collected, the predicted probability of an Earth impact diminished to practically zero. This is typical in the process of tracking Near-Earth Objects (NEOs) – asteroids,comets,or meteoroids with orbits that bring them within 1.3 astronomical units (CsE) of Earth, creating a theoretical collision risk.

Did you know? – ATLAS scans the entire night sky four times each night, searching for moving objects that could pose a threat to Earth.It’s designed for rapid detection of potentially hazardous asteroids.

However, subsequent analysis utilizing data from the James Webb Space Telescope (JWST) and the Center for the study of Near-Earth Objects at NASA’s Jet Propulsion laboratory (JPL) revealed a shift in the asteroid’s trajectory. experts now estimate a 4.3% chance of 2024 YR4 impacting the Moon. This figure has since been refined to 4%.

Why the Moon Now?

“the chance of hitting the moon has always been there,” explained a planetary scientist from Johns Hopkins University in Maryland in April 2025. “Back then it was less likely because Earth seemed like a bigger target.” more precise orbital calculations demonstrate that the orbital plane of 2024 YR4 has moved away from Earth and closer to the Moon.

This shift dramatically increases the likelihood of a lunar collision, which would be a visually spectacular event observable from Earth.Despite the relatively low probability, experts caution against dismissing the meaning of a 4% chance. The potential consequences, while not globally catastrophic, would be significant for lunar science and exploration.

The ongoing monitoring of 2024 YR4 underscores the importance of continued investment in NEO detection and tracking systems, ensuring we remain prepared for potential future threats from space.

Pro tip – Asteroid trajectories are constantly refined as more data becomes available. Initial predictions are frequently enough uncertain,and probabilities can change significantly over time.

Why did this happen? Initially detected on December 27, 2024, by the ATLAS telescope in Chile, asteroid 2024 YR4 was first calculated to have a 1% chance of impacting Earth on December 22, 2023. this risk quickly rose to 3.1%, causing brief public alarm. However, continued observation and analysis by the JWST and NASA’s JPL revealed a subtle but crucial shift in the asteroid’s orbit.

Who is involved? The key players in tracking and analyzing 2024 YR4 include the ATLAS team,the scientists at the JWST,and the experts at NASA’s Center for the Study of Near-Earth Objects at JPL. A planetary scientist from Johns Hopkins University provided expert commentary on the shift in trajectory.

What are the current predictions? As of April 2025, the probability of 2024 YR4 impacting Earth is considered practically zero. However, the probability of
