A new asteroid, designated as 2024 YR4, has been discovered and currently exhibits a slim chance of colliding with Earth, leading scientists to keep a close watch on it. This massive asteroid, measuring between 130 and 300 feet in width, was first detected on December 27, 2024, by the El Sauce Observatory in Chile. As of now, its likelihood of impacting Earth on December 22, 2032, is estimated to be around 1.6% to 1.9%, indicating a heightened level of concern.

The potential consequences of an impact from 2024 YR4 are severe, with experts warning that it has the energy equivalent to several megatons of TNT. This means that if it were to strike a populated area, the devastation could be substantial, equating to an explosion much larger than those of the atomic bombs dropped on Hiroshima and Nagasaki. Paul Chodas, director of NASA's Center for Near-Earth Object Studies, reassured the public, stating, “We are not worried at all, because there’s a 99 percent chance it will miss… But it deserves attention” Source.

According to the European Space Agency's analysis, asteroids of this size typically impact Earth every few thousand years. The current risk level rated on the Torino Impact Hazard Scale is Level 3, which signifies a close encounter warranting attention from the scientific community and the public. Past experiences with near-Earth objects such as Apophis, which at one point exhibited a 3% probability of impact in 2004, illustrate the necessity of ongoing observation and risk assessment Source.

Asteroid 2024 YR4 follows a highly elliptical orbit, swinging through the inner solar system. Its next close pass to Earth will occur in 2028. Future monitoring is crucial, as astronomers anticipate that as more data becomes available, the chances of a collision may decrease. Despite current estimates suggesting a slight increase in the calculated risk, experts remain optimistic. Andrew Rivkin, a planetary astronomer at Johns Hopkins Applied Physics Laboratory, noted, “The odds are very good that this will not hit Earth” Source.

NASA and various international space agencies continue to explore methods to mitigate potential asteroid threats. Options such as kinetic impactors capable of nudge an asteroid off its collision course are being considered. Besides kinetic options, theoretical plans like using lasers to vaporize part of the asteroid for deflection or employing gravity tractors are also under discussion. However, these require substantial funding and global cooperation.

While the prospect of a collision is alarming, scientists emphasize that the ability to track, predict, and potentially alter the trajectory of near-Earth objects allows humanity to develop a response strategy in case of impending threats. Monitoring continues, reminding us of the importance of readiness and public awareness regarding the activities of asteroids such as 2024 YR4.
