Webb Telescope: Asteroid's Odds of Hitting the Moon Rise to 4%

An asteroid that was briefly feared to hit Earth now has a nearly 4% chance of impacting the moon, according to new data from the James Webb Space Telescope. The asteroid, roughly the size of a 15-story building, had a previously calculated 3.1% chance of hitting Earth, a record high. While the threat to Earth has been eliminated, scientists are excited about the potential lunar impact, as it offers a valuable opportunity to gather data for planetary defense. Webb's observations also revealed unique physical properties of the asteroid.
