Asteroid 2024 YR4: A Potential Threat to Earth?
Discovered on 27 December 2024 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile, the near-Earth asteroid 2024 YR4 has quickly risen to the top of NASA’s list of cosmic risks. With an estimated size between 40 and 100 meters, this celestial object has captured the attention of astronomers worldwide.
The Torino Scale: A Level 3 Alert
The Torino Scale, a tool used to assess the probability and potential impact of near-Earth objects, has assigned 2024 YR4 a Level 3 rating.This classification signifies that the asteroid’s approach warrants close monitoring by astronomers. According to current calculations, there is a 1% or higher chance of a collision capable of causing a local disaster.
“Near approaching, the attention of astronomers requires,” the scale notes. This rare classification places 2024 YR4 in a category that demands vigilance and further analysis.
A History of Cosmic Threats
The Torino Scale ranges from zero (no risk of collision) to ten (certain collision with catastrophic consequences). Since its inception at the beginning of the century, only a handful of objects have reached Level 3 or higher. The highest level ever recorded was Level 4, briefly assigned to the asteroid Apophis in 2004. At the time, Apophis had a 2.7% chance of impacting Earth, though subsequent measurements downgraded its risk to zero.
While Apophis is significantly larger than 2024 YR4, the latter’s potential impact remains a cause for concern.
What’s Next?
As astronomers continue to monitor 2024 YR4, the focus will be on refining its trajectory and assessing the likelihood of an impact. The asteroid’s current path suggests a potential collision date of 22 December 2032, though this remains subject to change as more data becomes available.
