Trend Track
The idea of an asteroid hitting Earth is the stuff of Hollywood blockbusters, but in 2032, it might not be just science fiction. A recently discovered asteroid, 2024 YR4, has raised concerns due to its small—but real—chance of colliding with our planet. Before you start panicking, let’s break down what’s happening, what scientists are doing about it, and why there’s no need to worry just yet.
What’s the Deal with Asteroid 2024 YR4?
Asteroid 2024 YR4 was first detected on December 27, 2024, by astronomers using the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile. The asteroid is estimated to be between 40 to 90 meters in size, roughly the length of a football field. That might not sound massive compared to the dinosaurs’ extinction-causing asteroid, but it’s still big enough to cause significant damage if it were to hit Earth.
Initial calculations gave this asteroid a 1.3% chance of impact on December 22, 2032. That probability has since been updated to 2.3%—or roughly 1 in 43 chances—according to the latest observations. While that might sound alarming, it’s important to understand how asteroid risk assessments work.
How Do Scientists Predict Asteroid Collisions?
Astronomers use a system called the Torino Impact Hazard Scale, which rates asteroid threats from 0 to 10. Most asteroids fall at level 0, meaning no risk at all. Asteroid 2024 YR4, however, has been classified as a level 3 object, meaning it “deserves attention” but doesn’t warrant panic. In history, nearly every asteroid with an initial risk rating like this has later been determined to be harmless after further study.
This is because predicting an asteroid’s exact path is tricky. Small measurement errors can make a huge difference in long-term calculations. Over time, as astronomers track the asteroid more closely, they refine their estimates, and the risk usually decreases.
Could This Really Be Dangerous?
While the 2.3% impact probability is higher than usual for a newly discovered asteroid, it still means there’s a 97.7% chance that it will completely miss Earth. Even if it were to hit, its relatively small size means it wouldn’t be a world-ending event, but rather a localized disaster.
For reference:
The Tunguska event in 1908, caused by an asteroid of similar size, flattened 2,000 square kilometers of forest in Siberia.
The Chelyabinsk meteor in 2013 was only 20 meters wide but caused widespread damage and injured over 1,600 people due to its shockwave.
If 2024 YR4 were to hit, it would likely cause a regional disaster, not a global catastrophe.
What’s NASA Doing About It?
NASA, the European Space Agency (ESA), and other space organizations have been preparing for asteroid threats for years. In 2022, NASA successfully carried out the DART (Double Asteroid Redirection Test) mission, where a spacecraft intentionally crashed into an asteroid to alter its trajectory. This proved that we can change an asteroid’s path if needed.
If further observations confirm that 2024 YR4 poses a real risk, space agencies already have the technology to deflect it before it reaches Earth. Possible solutions include:
Kinetic impactors (like DART) to change its course.
Gravity tractors (a spacecraft slowly pulling the asteroid away).
Nuclear deflection (as a last resort).
What Happens Next?
Right now, astronomers are tracking 2024 YR4 closely. The asteroid is moving away from Earth, making it difficult to observe for the time being. However, it will be visible again in 2028, giving scientists another chance to refine its trajectory.
Most likely, further data will reduce the impact probability to nearly zero, just as has happened with many other asteroids in the past. Even in the unlikely scenario that it remains a risk, space agencies have several years to take action.
The Bottom Line: No Need to Panic
Asteroids passing close to Earth are not uncommon, and the fact that we can detect and track them years in advance is a huge advantage. While 2024 YR4 is getting attention due to its slightly higher-than-normal impact probability, history shows that these probabilities tend to decrease as more data is gathered.
With NASA, ESA, and other experts monitoring the situation and proven technology to deflect potential threats, there is no immediate danger. So, while “asteroid hitting Earth in 2032” sounds like a terrifying headline, rest assured that scientists have it under control.
For now, you can safely go back to your daily routine—no need to build a doomsday bunker just yet.
