2024 Yr4 is one of about 20,000 Apollo -type asteroids that orbite the sun from the same thing … [+]
The chances of asteroids of asteroid 2024 yr4 this week increased to 1-in-32 after the NASA Center for Object Studies near Earth updated the probability of impact-then dramatically fell to only 1-in-67 after some observations others.
On February 18, 2025, NASA Center for Study of the Object Near Earth
Updated the probability of asteroid impact to 3.1%, the highest ever recorded for an object of this size. However, according to NASA, subsequent data collected overnight reduced this probability to 1.5% since February 19, 2025.

What is 2024 yr4? Discovered on December 27, 2024, from the last system of the last asteroid land alarm in Chile, asteroid 2024 Yr4 measures approximately 130 to 300 meters (40 to 90 meters) in diameter. According to IAwn, his potential impact date is projected for December 22, 2032, with the “Risk Corridor” covering the Eastern Pacific Ocean, North America, the Atlantic Ocean, Africa, the Arabian Sea and South Asia.
Astronomers all over the world – and even the James Webb spatial telescope – are now busy making additional observations to try to refine the exact trajectory of 2024 years. The last full moon in the same region of heaven (Canis Major) had led to a lack of observations, which resulted in a gap of observations. However, observations have resumed this week and are already yielding results.

Uncertainty around 2024 years is simply in its latest discovery. 2024 Yr4 orbits the sun every four years, passing the Earth’s orbit once in orbit. Since it was discovered only in December, it has only been followed for a few months, a small part of its entire orbit. “The small part of the tracing creates great uncertainty about the place where the asteroid will be at any date away from the future,” said Richard Binzel, professor of planetary science at the Massachusetts Institute of Technology, in an email. “In 2032, this uncertainty happens to include the small land pepper in space.”
Close meeting
Binzel is the inventor of the degree of risk of Impact Torino, a tool for categorizing potential Earth’s impact events. Despite lowering his chance for an influence, 2024 Yr3 is still classified as 3 on a scale of 10, summarized as “a close meeting, deserving attention from astronomers”.
“While probability changes, there is no risk assessment,” Binzel said. “2024 Yr3 remains the degree of Torino 3.” However, Binzel points out that this category says “most likely, new telescopic observations will lead to re-determination at level 0.”
Something something of a race against the time after April, the asteroid will not be visible to the telescopes again until the end of 2028 when 2024 years further will come within the proximity of the Earth.
The region of uncertainty
“Finally, we expect the probability to fall to zero and reach the Torino 0 scale (all clear!),” Binzel said. “The region of uncertainty, which looks like a long spaghetti of the fetuccine string, shrinks as we get tracing data over a longer and longer part of the asteroid orbit.” Finally, this spaghetti range will shrink into a single grain because astronomers will have traced the full asteroid orbit.
An analogy is the follow-up of the hurricane, where, at the beginning, the path of a hurricane has great uncertainty, but becomes very well-defined as long as the storm is tracking. “Hurricane tracking can be refined within a few days or a week,” Binzel said. “For asteroids, it can take months or even years.”
What happens next
Many asteroids initially considered a possible threat have been reclassified as harmless after further analysis – and this is exactly what is already happening. “I look forward to that we will continue to see that the probability number jumps, we will even grow at last, we solve it as 0,” Binzel said, pointing out that it is merely the method of scientific measurement and the methods of calculating the orbit that are made in public. “It may seem confusing or disturbing, but it’s just the nature of this particular science,” he said. “Astronomers do not want to keep secrets, as everyone can look up. The sky is free for everyone.”
Although the moon absence from the sky of the evening makes it easier to observe 2024 years, our natural satellite is not completely outside the forest. According to NASA, current calculations estimate a probability of impact of 0.8%-a chance 1-in-125-that the asteroid does not hit the soil but the moon.
