NASA has increased the estimated chance of asteroid 2024 YR4 hitting Earth on December 22, 2032, to 3.1-percent, or about 1 in 32. This asteroid, discovered in December 2024, is between 130 and 300 feet wide. If it impacts Earth, it could release energy equivalent to 7.8 megatons of TNT, which is about 500 times more powerful than the bomb dropped on Hiroshima. The potential impact zone includes major cities like Bogotá, Mumbai, and Dhaka, affecting over 100 million people. Scientists plan to use the James Webb Space Telescope next month to gather more data before the asteroid becomes too faint to observe in April. The 3.1-percent chance is the highest ever given for an asteroid to impact Earth.
