Asteroid 2024 YR4, which was earlier seen as a threat to Earth, now appears to be on a collision course with the moon.
Since its discovery last year, the asteroid had caught the attention of the world after it was revealed there was a slim possibility it might hit the Earth in 2032.
Experts at the National Aeronautics and Space Administration (NASA) Center for Near Earth Object Studies have updated the 2024 YR4’s chance of hitting the Moon in 2032 to 4.3 per cent.
NASA updates 2024 YR4 risk
According to NASA, the possibility of 2024 YR4 hitting the moon was updated after data from the James Webb telescope and other ground-based telescopes.
“The Webb data improved our knowledge of where the asteroid will be on December 22, 2032, by nearly 20%. As a result, the asteroid's probability of impacting the Moon has slightly increased from 3.8% to 4.3%. In the small chance that the asteroid was to impact, it would not alter the Moon's orbit,” a post on NASA’s blog read.
Where is 2024 YR4 now?
According to NASA, the asteroid is now too far away to observe with telescopes. Further observations will be conducted by the US space agency in 2028, when the asteroid's orbit around the Sun brings it back closer to Earth.
As data comes in, the probability of the asteroid’s impact may change. An international team led by Maryland-based Dr. Andy Rivkin of the Johns Hopkins University Applied Physics Laboratory, made the observations about the asteroid in May using Webb's near-infrared camera.
Will asteroid 2024 YR4 hit Earth?
When the asteroid was first discovered in 2024, it had a very low probability of impacting the Earth. After investigation, NASA concluded that the asteroid would not pose a significant impact risk to the planet in 2032 and beyond.
When the asteroid was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ALERT), it was called ‘city destroyer’ online due to its speed, size, and the possibility of it hitting the Earth.
