A newly discovered asteroid, 2024 YR4, made headlines when early calculations suggested a 3.1% chance of hitting Earth in December 2032. However, with updated data, the probability has dropped significantly to just 0.28% (1 in 360).
Why the Impact Risk Changed
Scientists refine asteroid impact predictions as they gather more observations. NASA’s latest calculations, based on ground-based telescope data from February 19-20, helped refine 2024 YR4’s trajectory, reducing the likelihood of a collision.
🛰 Expert Analogy:
Tracking an asteroid is like predicting where a baseball will land the moment it’s hit—early estimates are uncertain, but precision improves with time.
What If 2024 YR4 Hit Earth?
🔹 Estimated Size: 40–90 meters wide
🔹 Potential Impact: Similar to the Tunguska Event (1908), which flattened 2,000 sq km of Siberian forest
🔹 Effects: City-level devastation, shattered windows for miles, and possible ocean-triggered waves
Learning from Past Asteroid Alerts
XF11 (1997) was falsely thought to pose a major risk, leading to panic before updated calculations ruled out an impact.
This led to the creation of the Torino Impact Hazard Scale, which categorizes asteroid threats from 0 (no risk) to 10 (certain impact).
Final Verdict
2024 YR4 is NOT a serious threat right now, but scientists will continue tracking it.
NASA & ESA monitor near-Earth objects and have planetary defense strategies like the DART mission, which proved that asteroid deflection is possible.
Should we worry? No. But should we keep monitoring? Absolutely.
