NASA scientists have revised estimates regarding the 'city-killer' asteroid 2024 YR4, which was initially believed to have a 20% chance of hitting Earth in 2032. Following statistical analyses and public meetings, the likelihood first rose to 3.1% before drastically dropping to only 0.005%. This asteroid, if it were to collide with Earth, could cause immense destruction equivalent to detonating 7.7 megatons of TNT. Initially earning a score of three on the Torino Impact Hazard Scale, it later received a score of zero, indicating no current threat.
NASA's assessments of 'city-killer' asteroid 2024 YR4 showed risk estimates fluctuating from 3.1% to 0.005%, reflecting uncertainty in its potential impact.
When asteroid 2024 YR4 was first discovered, it was assigned a 1.2% risk of collision, which later rose to 3.1% before being reduced to a negligible 0.005% chance.
