The possibility of asteroid 2024 YR4 striking Earth has been downgraded to nearly zero by NASA. First spotted in late 2024, earlier calculations suggested a collision with Earth could occur in December 2032, making it the riskiest asteroid ever detected. However, with continued astronomical observations, the likelihood of 2024 YR4 hitting Earth has now dropped to just 0.28 percent. After determining an asteroid's initial trajectory through ground-based observations, researchers use high-precision models of the solar system to predict its future path. As more data is collected, these predictions become more accurate.
