Overview

• Asteroid 2024 YR4, discovered in December 2024, has a 1.2% chance of colliding with Earth on December 22, 2032.
• The asteroid is categorized as a Level 3 threat on the Torino Scale, warranting attention but not immediate concern for global catastrophe.
• If it impacts Earth, the asteroid could cause localized devastation equivalent to eight megatons of TNT, with significant risks to urban areas or coastal regions.
• NASA and ESA-led groups, including the International Asteroid Warning Network and Space Mission Planning Advisory Group, are tracking its trajectory and planning potential mitigation strategies.
• Astronomers expect further observations to refine its orbit and likely reduce the impact probability, with the next key tracking opportunity anticipated in 2028.
