NASA Refines Asteroid 2024 YR4's Trajectory, Slightly Increases Lunar Impact Probability
NASA's latest observations of asteroid 2024 YR4 have slightly increased its probability of impacting the Moon in 2032, while confirming no significant threat to Earth.
NASA's James Webb Space Telescope (JWST) has provided new data on asteroid 2024 YR4, leading to a refined understanding of its trajectory. The asteroid, measuring between 53 and 67 meters in diameter, was initially discovered in late 2024. Early calculations indicated a 3.1% chance of colliding with Earth by December 22, 2032. However, subsequent observations have ruled out any significant impact risk to our planet.
The latest JWST data has improved the precision of the asteroid's predicted position by nearly 20%, resulting in a slight increase in the probability of a lunar impact from 3.8% to 4.3%. Despite this, experts assert that even if 2024 YR4 were to strike the Moon, it would not alter the Moon's orbit or pose a threat to Earth.
Asteroid 2024 YR4 is currently too distant for observation but is expected to become visible again in 2028. This will allow scientists to gather more data on its composition and trajectory, enhancing our understanding of near-Earth objects and planetary defense strategies.
