Asteroid 2024 YR4 has recently become a focal point of concern in the scientific community due to its unusually high risk of colliding with Earth. This space rock, spotted late last year and reported on December 27, 2024, to the Minor Planet Center, is considered one of the moast hazardous asteroids detected as the notorious Apophis was discovered in 2004.
The Minor Planet Center serves as the official authority for observing and reporting new asteroids, comets, and othre small bodies in the solar system. The object, designated 2024 YR4, is currently being monitored closely by astronomers worldwide. The potential impact zone is estimated to be around 1 million miles from Earth, which, while not immediately catastrophic, would still be a significant event.
In the case of Apophis, further observations allowed astronomers in 2021 to rule out the possibility of an impact when the asteroid makes a close flyby to Earth in 2029 and again in 2036. Scientists expect a similar outcome for 2024 YR4 as it continues to be scrutinized.
Should any asteroids ever pose a serious threat to Earth, the world’s space agencies have been proactive in building a planetary defense against dangerous space rocks. Richard Moissl, head of the European Space Agency’s Planetary defense Office, stated, “We aren’t just waiting for an asteroid to strike. We are taking active measures to help Earth defend itself against a potential impact.”

Asteroid 2024 YR4: A Close call with Earth
A new asteroid, designated 2024 YR4, has caught the attention of NASA and other astronomers when it rose on the U.S. Space Agency’s Sentry Impact Risk Table, which tracks any known asteroids with a non-zero probability of hitting Earth. Based on projections, the asteroid has little more than a 1% chance of impacting Earth on Dec. 22, 2032. Asteroid 2024 YR4 also rates 3 of 10 on the Torino Impact Hazard Scale, a method for astronomers to categorize and rate the threat of near-Earth objects.
For these reasons, the asteroid is one that astronomers and public officials are keeping their eyes on until it’s likely to be ruled out as a threat.
Remember Apophis? Asteroid once posed even bigger threat
Asteroid 2024 YR4’s rating of 3 on the Torino Scale is the second-highest an asteroid has ever reached after the notorious Apophis briefly hit a rating of 4 many when it was first discovered. The risk of Apophis impacting Earth during its 2029 flyby even rose as high as 2.7% on the Sentry Impact Risk Table.
The Torino rating and impact likelihood made Apophis one of the most threatening asteroids ever observed. But as often happens, that initial dire assessment has since changed as astronomers tracked it and learned more about the orbit of the asteroid.

However, recent advancements have shown that humanity may finally have a viable defense against these celestial threats. NASA’s Double Asteroid Redirection Test (DART) mission,conducted in september 2022,demonstrated that it is possible to nudge an incoming asteroid out of harm’s way by slamming a spacecraft into it. Launched in November 2021, the DART spacecraft embarked on a journey that would span over 10 months before it made contact with its target. On September 26, 2022, DART successfully crashed into Dimorphos at a velocity of approximately 14,000 mph. Despite the tiny asteroid posing no immediate threat to Earth, the mission was a resounding success. NASA had set out to test the feasibility of using kinetic impactors as a means of deflecting potentially hazardous asteroids. | Aspect | Details | Following the impact, extensive observations were conducted to monitor the changes in Dimorphos’ orbit. The mission provided invaluable data on how the surface of an asteroid reacts to such an impact and how it affects the asteroid’s trajectory. This information is crucial for developing more advanced asteroid deflection strategies in the future. The DART mission is part of a broader effort to study and mitigate asteroid impacts. The European Space Agency (ESA) is also actively involved in planetary defense. In July, ESA The Future of Planetary Defense
