Scientists warn asteroid 2024 YR4 could collide with Earth in 2032 raising urgent concerns about planetary defense

The idea of a massive asteroid slamming into Earth sounds like something straight out of a sci-fi blockbuster, but this time, it’s not just fiction.

A recently discovered space rock, named 2024 YR4, is making headlines for all the wrong reasons.

Scientists are keeping a close watch on this asteroid, as calculations suggest it could be heading straight for our planet.

A Growing Concern: What We Know About 2024 YR4

Spotted in December last year, 2024 YR4 measures between 130 to 300 feet (40 to 90 meters) in diameter—making it potentially larger than the Statue of Liberty.

Since its discovery, experts have been monitoring its trajectory, and recent updates have sparked fresh concerns.

Last week, scientists revised the probability of impact to 1-in-43 (or 2.3%), with a possible collision date of December 22, 2032.

While that may sound like slim odds, it’s significant enough to raise alarm bells among planetary defense experts.

Time is Running Out for a Deflection Mission

Asteroid deflection is not as simple as it seems. Dr. Robin George Andrews, a volcanologist and author, has pointed out that humanity has less than eight years to figure out a plan.

The problem? A proper deflection mission could take a decade or more to develop and execute.

NASA’s Double Asteroid Redirection Test (DART) mission successfully demonstrated that a spacecraft could alter an asteroid’s trajectory.

In 2022, the DART spacecraft intentionally collided with Dimorphos—a harmless space rock—shortening its orbit by more than half an hour.

While this proved that asteroid deflection is possible, 2024 YR4 presents new challenges that may render a similar approach ineffective.

Why Stopping 2024 YR4 Might Not Be Easy

While the DART mission was a success, scientists caution that not all asteroids respond the same way to impact deflection.

One major concern is that many asteroids, including 2024 YR4, may not be solid rocks but rather “rubble piles” held together by weak gravity.

If a spacecraft were to collide with such an asteroid, the impact could scatter debris in unpredictable directions—some of which might still threaten Earth.

Dr. Andrews warns that if we don’t act soon, we risk running out of options.

“We don’t have much time,” he stated.

“If we try to deflect it too late, we might push it into another impact zone instead of saving the planet.”

What Happens If 2024 YR4 Hits Earth?

If 2024 YR4 were to strike our planet, the consequences would depend on its size and impact location.

A best-case scenario would see it landing in an uninhabited desert or an ocean, causing minimal harm.

However, if it were to hit a city, the destruction could be catastrophic, potentially leveling entire neighborhoods.

Historically, similar-sized impacts have been devastating.

The Tunguska event of 1908 flattened 830 square miles of forest in Siberia and was caused by an asteroid roughly the same size as 2024 YR4.

While it occurred in a remote area, the event demonstrated the sheer power such an impact could unleash.

How Can We Prevent a Catastrophic Impact?

Scientists have proposed several methods to divert or neutralize potentially hazardous asteroids. Some of the most promising ideas include:

1. Multiple Impacts

A series of smaller impacts could help alter the asteroid’s path without breaking it apart into dangerous fragments.

2. Nuclear Detonation

A nuclear explosion near the asteroid could change its trajectory, though this method risks creating smaller but still dangerous debris.

3. Ion Beam Deflection

A spacecraft could use ion thrusters to push the asteroid gradually over time, changing its course subtly but effectively.

4. Gravity Tractor

A spacecraft positioned near the asteroid could use gravitational pull to slowly nudge it off its collision path without making direct contact.

What’s Next for 2024 YR4?

For now, scientists are working to refine their calculations and better understand 2024 YR4’s composition and trajectory.

As Dr. Andrews explained, the odds of impact remain low and may decrease further as more data is collected.

Still, the asteroid serves as a reminder of Earth’s vulnerability to cosmic threats.

NASA and other space agencies continue to research ways to protect our planet from potential asteroid collisions.

But as history has shown, early detection is key—and the clock is ticking.
