NASA Raises Alarm: Asteroid 2024 YR4's Chance of Hitting the Moon Doubles!

In a startling update, NASA has revealed that the chances of asteroid 2024 YR4 striking the Moon during Christmas 2032 have more than doubled! Originally identified as one of the most perilous objects in our Solar System, the likelihood of this cosmic rock hitting Earth was previously estimated at a mere 0.004 percent. However, experts have now reassessed the situation and placed the odds of a collision with our Moon at approximately 3.8 percent, nearly one in 25.

According to NASA's Center for Near Earth Object Studies at the Jet Propulsion Laboratory, the updated probabilities were released this week. While there remains a substantial 96.2 percent chance that the asteroid will miss the Moon completely, if it does collide, NASA assured that it will not affect the Moon's orbit.

Asteroid 2024 YR4 was initially detected by an automatic telescope on Christmas Day of last year, and within days, scientists determined its potential threat to Earth. As more observations were conducted, it became clear that the asteroid could also potentially impact the Moon, prompting an increase in the probability of a lunar encounter from an original estimate of just 0.3 percent.

The James Webb Space Telescope has played a critical role in studying 2024 YR4's characteristics, using its NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) to gather data on the asteroid's size and composition. Preliminary analysis indicates that this asteroid is rather unique. The thermal properties—the rate at which it heats and cools—differ significantly from those of larger asteroids. This peculiar behavior suggests a combination of its rapid rotation and a surface lacking fine-grained sand, likely dominated by larger rocks.

NASA estimates the size of 2024 YR4 to be approximately 60 meters (200 feet) wide. Should this rock impact the Moon, the result would be a relatively small crater, far less dramatic than the massive South Pole-Aitken basin.

Looking ahead to 2032, there's a chance that a permanent human presence will exist on the Moon, as nations including the US, Russia, and China are making plans to establish their footholds there. While the likelihood of humans being in danger from an asteroid impact remains infinitesimally small, it has sparked a wave of interest and conversation about planetary defense and the future of lunar exploration.

With ongoing advancements in asteroid tracking and characterization, the scientific community eagerly awaits to see what additional insights emerge regarding 2024 YR4 and similar celestial objects. As we monitor this cosmic visitor, the fascination with and study of our solar neighbors continue to deepen—even as we prepare for an exciting future on the Moon!
