The James Webb Space Telescope has taken another look at the potential "city-killer" asteroid 2024 YR4 and found its chances of hitting the moon in December 2032 have increased to 4.3%.
The James Webb Space Telescope (JWST) has taken its final look at the potentially hazardous asteroid 2024 YR4, at least until the potentially hazardous space rock darkens Earth's cosmic doorstep again in 2028. The latest observations reveal that, while Earth faces no risk of impact from the asteroid for the foreseeable future, the moon might not be so lucky.
The new observations, taken with JWST's Near-Infrared Camera in May, allowed scientists to calculate the space rock's trajectory with the greatest precision yet, according to a NASA statement. The new predictions suggest there's a 4.3% chance that asteroid 2024 YR4 will collide with the moon on Dec. 22, 2032 — up from the 3.8% odds of a lunar impact reported after JWST initially imaged the space rock in March.
"As data comes in, it is normal for the impact probability to evolve," NASA representatives wrote in the statement. "NASA expects to make further observations when the asteroid's orbit around the Sun brings it back into the vicinity of Earth in 2028. "
