Protecting the Earth from Asteroid 2024 YR4 Using Nuclear Explosives
Asteroid 2024 YR4, approximately the size of a football pitch, has been identified as a potential cosmic threat to our planet. Currently, approximately 27 million miles away from Earth, the asteroid was initially estimated to have a one in 83 chance of directly impacting our planet in 2032. However, the latest findings indicate that Earth impact is no longer a concern, but the asteroid carries a 4% chance of striking the Moon that year.
The potential impact of an asteroid collision cannot be underestimated, as demonstrated by the Tunguska event in 1908. If 2024 YR4 were to hit the Moon, the impact would release energy equivalent to about 6 million tons of TNT, forming a crater over half a mile wide. This impact could eject debris that might endanger satellites in low-Earth orbit for days to months and possibly create a rare meteor shower visible from Earth. It also poses a hazard to spacecraft orbiting or planned to operate near the Moon, such as NASA’s Lunar Gateway, as well as lunar surface missions.
The European Space Agency (ESA) is closely monitoring 2024 YR4. However, current discussions do not mention any active or proposed attempts to deflect the asteroid from its potential lunar impact. The asteroid is currently behind the Sun from Earth’s perspective, limiting observations until around 2028, after which trajectory predictions will improve and better inform any necessary mitigation planning.
The Space Mission Planning Advisory Group, chaired by the ESA, will discuss the latest findings and assess the impact risk at an upcoming meeting in Vienna. Potential deflection strategies may need to be considered by 2028, before the asteroid vanishes from view, offering a brief window for preventive measures.
Dr. David Whitehouse, an astronomer, has warned of this potential threat and compared the odds of this asteroid strike to winning the lottery, albeit in reverse. His warnings underscore the need for vigilance and proactive measures to protect our home planet from potential catastrophic events. The impending encounter with asteroid 2024 YR4 serves as a reminder of the precarious nature of our existence in space.

- In light of the potential lunar impact of Asteroid 2024 YR4, discussions about deflection strategies are gaining importance, as any collision could have severe consequences for satellites, lunar spacecraft, and the Moon's surface missions, much like the Tunguska event demonstrated on a smaller scale.
- Ongoing monitoring of 2024 YR4 by the European Space Agency (ESA) and other space agencies highlights the need for environmental-science research to better understand and mitigate potential cosmic threats, while also promoting advancements in space-and-astronomy and health-and-wellness (to protect lives and infrastructure in space).
