About seven years from now, in 2032, an asteroid orbiting the Solar will fly so near Earth that it has slightly over 1 p.c likelihood of affect. The asteroid, named 2024 YR4, stands out as the one near-Earth asteroid out of the over 37,000 at the moment acknowledged to have an effect likelihood above 1 p.c.
Scientists calculated this likelihood after the asteroid was reported on December 27, 2024 at a telescope in Chile belonging to the Asteroid Terrestrial-impact Final Alert System (ATLAS), funded by NASA.
Round that point, 2024 YR4 had already made a detailed method to our planet at 829,000 kilometers (about 515,116 miles) away, giving scientists a window to estimate when it’ll return and the way seemingly it’s to strike Earth. As of January 30, 2025, it has a 1.2 p.c likelihood to affect Earth on December 22, 2032.
What Menace Does 2024 YR4 Pose?
This discovery is nothing to scoff at — it places Asteroid 2024 YR4 at Stage 3 on the Torino Influence Hazard Scale, a software used to categorize potential Earth affect occasions with a scale starting from 1 to 10.
Stage 1 area objects — within the Inexperienced Zone, or class Regular — are widespread, noticed a number of occasions a yr and never thought-about a hazard to the planet. Stage 2 to 4 objects — within the Yellow Zone, or class “Meriting Consideration by Astronomers” — current a marginal risk, however will almost certainly be introduced all the way down to a Stage 0 (no hazard) when reassessed.
Solely three objects have ever reached the Yellow Zone on the Torino Scale since its implementation in 1999. From February to Could 2006, the asteroid 2004 VD17 reached Stage 2 (however was lowered to 1 after which 0 within the following months). In December 2004, the asteroid 99942 Apophis stirred momentary panic because it reached Stage 4, setting a report for the best ranking ever on the Torino Scale. After reassessments, although, it went all the best way all the way down to Stage 0 inside two years.
The final of the three, after all, is the recently-discovered Asteroid 2024 YR4 at Stage 3. If the asteroid (estimated to be between 130 and 330 ft broad) had been to collide with Earth, it might result in an air burst — exploding because it enters the environment — or an affect crater. In both state of affairs, Asteroid 2024 YR4 would convey regional devastation to the Earth’s floor.
Influence Occasions All through Historical past
Scattered moments in historical past have hinted on the grave nature of an affect occasion. This may be seen first-hand with websites just like the 66-million-year-old Chicxulub crater within the Yucatán Peninsula, Mexico (considered the explanation for mass dinosaur extinction) and the 50,000-year-old Meteor Crater in northern Arizona.
In more moderen historical past, a mysterious explosion in rural Russia on June 30, 1908 turned out to be the results of an air burst from an asteroid; the Tunguska occasion, as it’s now referred to as, razed over 80 million bushes and resulted within the deaths of three individuals, in line with eyewitness accounts. This might have correlated to an 8 on the Torino scale.
Nearly a century later, on February 15, 2013, a smaller air burst occurred over Chelyabinsk, Russia, creating a large shockwave that broken a number of buildings and injured round 1,200 individuals (no deaths had been reported).

No Must Panic
So, must you instantly begin to freak out about Asteroid 2024 YR4? The reply, it appears, is a assured “no” as scientists have reassured. Initially, primarily based on the present estimates, there may be nonetheless a 99 p.c likelihood it’ll move by Earth.
However the primary purpose scientists consider individuals ought to preserve their composure is as a result of there’s a good likelihood 2024 YR4 can be reclassified all the way down to Stage 0 when noticed sooner or later, the identical end result for 2004 VD17 and 99942 Apophis.
The asteroid is now transferring away from Earth and can be too distant to watch by April 2025. A number of years later, scientists can have one other likelihood to watch 2024 YR4 as it’ll return to the neighborhood of Earth in June 2028.
Though a detailed eye will have to be saved on the asteroid when it returns, the individuals of Earth can breathe a brief sigh of reduction for now, understanding that the prospect of affect will seemingly get slimmer with time.
