NASA Tracks Asteroid 2024 YR4, Collision Risk Rises

Asteroid 2024 YR4, dubbed the 'city-killer,' has risen to the top of NASA's impact risk list with a collision probability of 1-in-43 to 1-in-48 for December 22, 2032. Recent observations from the Gemini South Telescope in Chile have provided detailed images of the asteroid, which measures between 130 and 300 feet wide. Former astronaut Chris Hadfield warned that if YR4 were to collide with Earth, the explosion could be equivalent to 7.7 megatons of TNT, causing widespread devastation. Despite the alarming statistics, scientists emphasize that these estimates fluctuate as they refine the asteroid's orbit, and a potential intercept mission may be considered if the risk remains high. Currently, YR4 is being closely monitored, with the James Webb Space Telescope set to contribute to ongoing observations. Experts highlight the urgency of addressing the asteroid's threat, given the limited time available for any deflection mission planning.
