The chances of an asteroid known as the 2024 YR4 crashing into Earth in seven years have fluctuated recently, but experts are still not prepared for the worst.
At the end of 2024, a NASA-funded telescope in Rio Hartado, Chile, first discovered the 2024 YR4, and a month later scientists say the asteroid would hit Earth in December 2032. We concluded that there is a possibility of more than 1%.
When scientists first reported their discoveries in January, they hoped that the asteroid’s future trajectory and probability of change would change as observational data were collected and analyzed. That’s exactly what happened.
On Tuesday, astronomers reported that the probability of a 2024 YR4 colliding with Earth increased to about 3%. This is unusual for small asteroids 130-300 feet wide. By Wednesday, its impact rating had dropped to 1.5%.
“However, people shouldn’t worry too much about it because impact odds remain small,” said Davide Farnocchia, a navigational engineer at NASA’s Jet Propulsion Institute and a nearby-earth object research center. It’s there.
Is it normal for the impact risk to increase very quickly?
Yes, there is a scientific reason why the change in impact probability suddenly increases. However, the probability can also be suddenly reduced.
The first is, “The possibility of a collision with the Earth cannot be ruled out, so there may be a slight possibility of impact. [but] At some point, the probability is zero,” Farnockia said.
Once an asteroid is identified, scientists are unable to pinpoint an exact future location, but instead they can collect data to predict where it is within range. If that range overlaps with Earth, it reported NASA SpaceFlight when there is a possibility of a collision.
More observational data makes astronomers’ predictions of asteroid trajectories and future locations more accurate.
The current extent of the 2024 YR4 trajectory is based on hundreds of collected observations, but is still evaluated, so the range is large and currently overlaps with Earth. That’s why the likelihood of impact is increasing.
As astronomers continue to collect data, the range can be significantly reduced, no longer overlapping with Earth, and there is zero chance that the 2024 YR4 will hit the planet.
The current trajectory of YR4 in 2024 is almost linearly away from Earth, and astronomers will continue to collect observational data until they are out of sight. They will need to track the asteroid collision course and future locations until early April.

Where will the asteroid collide?
If the asteroid’s trajectory is unlikely to connect to Earth, the impact point can be somewhere along the “risk corridor” that crosses the Eastern Pacific, South America, the Atlantic, the Arabian Sea and South Asia. International Asteroid Warning Network.
Have you ever experienced an asteroid event like this before?
Yes, astronomers point to the asteroid 99942 Apophis, 1,099 feet wide, was first identified in 2004.
At the time of the first sighting, Apophis was one of the most dangerous asteroids in the sky, with the threat of hitting barrels towards Earth in 2029.
During the initial assessment of impact risk, Apophis reached a Turin Scale 4 rating. This is a measure to classify potential Earth impact events.
Scale 0-10 can be used to achieve certain conflicts, ranging from no danger (Turino scale 0), normal (Turino scale 1), attention by astronomers (Turino scale 2-4), and threats (Turino scale 5-7). It extends to. (Turino scale 8-10).
Collecting further observational data and assessments, scientists have now ruled out the probability of Apophis’ impact, but in 2068 there was little chance of shock.
Regarding the 2024 YR4, it is currently classified as Turin 3.
It is rare for an asteroid to be evaluated on the Turin Scale 3. This is because the classification occurs only on asteroids above 65 feet with an impact probability of over 1%.
If this asteroid hits Earth, it could burn into the atmosphere and become a much smaller metstone before it lands.
According to the US Geological Survey, slightly larger asteroids can pass through the atmosphere, but crash at locations that cause minimal or immediate damage. Many met stones end up in the ocean or open areas.
