The asteroid, up to 90 meters across, was first discovered in December 2024 and is currently ranked three on the Torino Impact Hazard Scale, which measures the risk of space objects on a scale of 0 to 10.
Despite the increase, NASA expects further observations to reduce the risk.
“Several objects have risen on the risk list before ultimately being reassigned to 0 as more data becomes available,” the agency stated.
Many previously concerning asteroids have been removed from threat lists after refined calculations showed they would miss Earth.
If an asteroid were on course for impact, scientists have proposed several deflection strategies, including crashing a spacecraft into it or using nuclear explosions to alter its trajectory.
However, experts warn that Earth remains underprepared for a major asteroid strike, as no global defence system is currently in place.
The discovery of 2024 YR highlights the importance of continued monitoring of near-Earth objects.
NASA and other space agencies are working to track potential threats and develop mitigation plans.
While the current risk remains low, ongoing research will provide more clarity in the coming years.
