NASA researchers say an asteroid known as 2024 YR4 now has about a 1.5% chance of hitting Earth in 2032, a decrease from a record high estimate the day prior.
NASA’s Jet Propulsion Laboratory said Tuesday that 2024 YR4 had a 3.1% chance of impact, but astronomers lowered the estimate on Wednesday after darker skies and increased visibility allowed them to take a better look at the asteroid. However, the European Space Agency (ESA) estimates the likelihood to be at 2.8% as of Wednesday.
The asteroid is estimated to be between 130 to 330 feet wide, and astronomers believe it could plow into the planet on Dec. 22, 2032.
There is also a 0.8% chance it could slam into our moon that day instead, according to NASA.
The International Asteroid Warning Network (IAWN) said the following regions on Earth are at risk of being hit by the asteroid in 2032: the eastern Pacific Ocean, northern South America, the Atlantic Ocean, Africa, the Arabian Sea and South Asia.
The risks to Earth if the asteroid does collide with the planet are uncertain at the moment as its mass and potential impact location are unknown. As The New York Times notes, this could lead to a variety of possible scenarios from leveling a city to landing in the ocean and causing relatively little harm.
CBS News space consultant Bill Harwood said that the impact would be “catastrophic” if the asteroid landed in a populated area, but the damage wouldn’t be global.
“It wouldn’t be something like the rock that killed the dinosaurs,” Harwood said. “It wouldn’t affect the global climate, but it would certainly be a disaster of every proportion. So we’re all hoping that doesn’t happen.”
While 2024 YR4′s risk level on Tuesday was the highest ever recorded, it’s overwhelmingly likely that the asteroid misses Earth. However, the IAWN notifies the public of an asteroid anytime there is a 1% chance or above of impact, which is extremely rare.
The last time an asteroid met this threshold was in 2004, when asteroid Apophis’ probability of hitting Earth in 2029 was raised to 2.7%. After its 2004 discovery, astronomers tracked Apophis, estimated to be about 1,100 feet across, to better understand its path. NASA now says there is no risk of Apophis striking Earth for at least a century.
