Upping the Odds: A Potentially Hazardous Asteroid Headed Our Way in 2032
While it may not rival the dramatics of Don’t Look Up, a recent update from astronomers significantly boosts the chances of a direct hit from a giant asteroid on Earth. This asteroid, known as 2024 YR, has rocketed to the top of impact risk lists on both sides of the Atlantic.
The Updated Odds
NASA’s Center for Near Earth Object Studies (CNEOS) calculates a 2.3% chance of 2024 YR striking Earth in 2032, a one-in-43 probability. Just a week ago, the European Space Agency (ESA) gave the asteroid a 1.3% chance of colliding with the planet on December 22nd of that year, the day it will make its closest approach to Earth. This puts the likelihood of it passing without incident at approximately 99%.
The Size and Scale of the Threat
At up to 300 feet (90 meters) in width, the asteroid is similar in size to the Tunguska asteroid that flattened about 830 square miles (2,150 sq km) of Siberian forest in 1908. This comparison underscores the potential consequences if it were to impact Earth.
Astronomers Calm Public Concerns
Despite the increased odds, astronomers assure there is no immediate cause for panic. The asteroid now holds a rare Tier 3 rating on the Torino Impact Hazard Scale, indicating a low probability of impact. Such fluctuations are common and often result in a revised assessment as more data becomes available.
In a YouTube video titled “How Asteroids Go from Threat to No Sweat,” ESA explains that the likelihood of 2024 YR hitting Earth will likely drop significantly with future data updates. NASA’s planetary defense coordination office agrees, noting that previous asteroids of similar concern were reclassified to zero risk after further observations.
The Need for Continued Monitoring
Colin Snodgrass, professor of planetary astronomy at the University of Edinburgh, emphasizes the importance of continued monitoring. “Most likely, this one will pass by harmlessly. However, until we can confirm this, it deserves extra attention with telescopes. The longer we follow its orbit, the more accurate our future predictions of its trajectory become.”
Historical Context of Asteroid Threats
Recent history provides examples of how high-risk asteroids have evolved into non-threats. The asteroid 99942 Apophis, discovered in 2004 and larger than the Eiffel Tower, once carried a Tier 4 risk but was later determined to pose no threat on any of its close passes for the next 100 years.
Preparedness and Technological Advances
Even should 2024 YR continue on a trajectory toward Earth, humanity’s technological advancements offer hope. NASA’s Dart mission in 2022 successfully altered the path of a large asteroid by crashing a spacecraft into it. This demonstration proves that we have the capability to defend Earth from similar threats if necessary.
“This asteroid is of the scale that a mission like Dart could be effective, if required. We have the technology, and it has been tested,” asserts Snodgrass.
Conclusion
While the arrival of 2024 YR in 2032 isn’t cause for alarm yet, the situation calls for continued vigilance and scientific research. Technological advancements and past successes in planetary defense give us confidence in our ability to address any future threats. As our knowledge deepens, so too does our determination to preserve our planet.
