Asteroid 2024 YR4: A 1.2% Chance of Earth Impact in 2032
On December 27,2024,the Asteroid Terrestrial-Impact Last Alert System (ATLAS) detected a newly discovered asteroid, designated 2024 YR4, approximately 829,000 kilometers from Earth. With a diameter estimated at 55 meters (ranging between 40 and 100 meters), this space rock has sparked global interest due to its 1.2% chance of colliding with Earth on December 22, 2032.
While the probability of impact is low—1 in 83, or a 98.8% chance of a miss—the asteroid has been assigned a level 3 on the Torino Scale, indicating it “requires astronomers’ attention.” However, experts predict that further observations will likely downgrade it to level 0, meaning “no danger.”

- Conclusion
If 2024 YR4 were to strike earth, it would release an estimated 8 megatons of energy—equivalent to 500 Hiroshima atomic bombs. While not large enough to pose a global threat, its impact could be comparable to the 1908 Tunguska event, wich flattened over 80 million trees across 2,000 square kilometers in Siberia.
The asteroid’s composition will determine the exact outcome. If it’s a loose cluster of rocks, it could cause an “air burst” high in the atmosphere, generating a powerful pressure wave and extreme heat. If it’s a solid rock or metal, it could create a crater up to one kilometer in diameter, similar to Arizona’s Barringer Crater, with widespread damage extending 50 kilometers.
Current Observations and Future Monitoring
Until February 2025, 2024 YR4 will move too far from Earth to be observed by telescopes. However, scientists will have a better opportunity to study it in 2028, when it approaches within 8 million kilometers of our planet. This close pass will allow researchers to determine its exact size and composition, refining estimates of potential damage.
According to David Rankin of the Catalina Sky Survey project, any potential impact would likely occur in a region spanning the Pacific Ocean to South America, the Atlantic Ocean, Central Africa, and northern India. However, he emphasizes that the asteroid’s path remains uncertain, and ongoing observations will refine predictions.
Humanity’s Defense Mechanisms
Even in the unlikely event of a collision, humanity is not defenseless. In 2022, NASA’s DART mission successfully demonstrated the ability to alter an asteroid’s trajectory by crashing a spacecraft into it. If necessary, similar technology could be deployed to divert 2024 YR4 away from Earth.

While the odds of impact are slim, 2024 YR4 serves as a reminder of the importance of planetary defense. As scientists continue to monitor its trajectory, humanity can rest assured that we are not entirely powerless against the threats posed by near-Earth objects.“Mission Armageddon”: Amateur Astronomer Captures DART Probe’s Collision with Dimorphos
An amateur astronomer has captured and published stunning videos of NASA’s DART probe colliding with the moon Dimorphos, marking a notable milestone in planetary defense efforts. The footage, dubbed “Mission Armageddon,” showcases the dramatic moment of impact, providing a rare glimpse into humanity’s first attempt to alter the trajectory of a celestial body.
The DART (Double Asteroid Redirection test) mission, launched by NASA, aimed to test whether a spacecraft could successfully deflect an asteroid by crashing into it. Dimorphos, a small moon orbiting the asteroid Didymos, was the target of this groundbreaking experiment. The collision, which occurred in September 2022, was designed to assess the feasibility of using kinetic impactors to protect Earth from potential asteroid threats.
The amateur astronomer’s videos have since gone viral,offering a unique perspective on the event.The footage highlights the probe’s final moments as it approached Dimorphos at a staggering speed of 14,000 miles per hour, culminating in a bright flash upon impact.
A History of Asteroid Concerns
This is not the first time an asteroid has sparked global concern. as an example, Asteroid Apophis, discovered in 2004, was initially rated at level four on the Turin Scale, a system used to categorize the impact hazard of near-Earth objects. Early calculations suggested a 1.6% chance of collision with Earth in 2029. However, subsequent observations ruled out the possibility of impact not only in 2029 but also in 2036 and 2068.
Similarly, asteroid 2024 YR4 has recently drawn attention due to its relatively high risk of collision with Earth. While the current probability is significant from an astronomical standpoint, experts believe further observations will likely reduce the threat.
The Torino Scale: Assessing Asteroid Threats
the Torino Scale is a critical tool for evaluating the potential danger posed by near-Earth objects. It ranges from 0 (no hazard) to 10 (certain collision with catastrophic consequences). Asteroid 2024 YR4 is currently rated at level three, indicating a close encounter with a 1% or greater chance of collision capable of causing regional devastation.
| Asteroid | discovery Year | Torino Scale Rating | Potential impact Year |
|———————|——————–|————————-|—————————|
| Apophis | 2004 | 4 | 2029, 2036, 2068 |
| 2024 YR4 | 2024 | 3 | 2032 |
what’s Next for planetary Defense?
The success of the DART mission has paved the way for future planetary defense initiatives. NASA and other space agencies are now exploring additional methods to mitigate asteroid threats, including gravity tractors and nuclear deflection.
