Overview

• Asteroid 2024 YR4, discovered in December 2024, has an estimated size of 40 to 90 meters and could potentially impact Earth on December 22, 2032.
• NASA's initial calculations raised the asteroid's impact probability to 3.1%, the highest ever for an object of its size, but subsequent observations have reduced it to 1.5%.
• The asteroid's current risk rating on the Torino Scale is 3, signifying a close encounter that warrants continued monitoring by astronomers worldwide.
• Most potential impact scenarios fall over water, but the 'risk corridor' includes major cities like Bogota, Lagos, and Mumbai, raising concerns about localized destruction.
• Efforts to refine the asteroid's trajectory are ongoing, with telescopes like the James Webb Space Telescope and others gathering data to further lower the uncertainty.
