asteroid 2024 YR4: A Potential Threat to earth in 2032
in December 2032, earth could face a close encounter with a newly discovered asteroid, 2024 YR4, which has a more than 1% chance of colliding with our planet. This asteroid, discovered on December 27, 2023, by the Atlas telescope, has been classified as a Level 3 on the Torino Impact Hazard scale, a system used to assess the risk of asteroid impacts.
The Torino Scale ranges from 0 (no risk) to 10 (certain catastrophic collision), with level 3 indicating a “close encounter requiring attention from astronomers and the public.” This classification places 2024 YR4 among the rare asteroids that warrant significant monitoring.
Currently, 2024 YR4 is approximately 45 million kilometers from Earth and is at the top of the European Space Agency (ESA)‘s crash risk list. Its diameter is estimated to be between 40 and 100 meters, a size capable of causing significant regional damage if it were to collide with Earth. For context,an asteroid of this size strikes Earth roughly once every thousand years.
The only asteroid to have surpassed 2024 YR4 in risk level was Apophis, which briefly reached Level 4 on the Torino Scale in 2004.Though, subsequent observations confirmed that Apophis posed no threat for at least the next century, and its risk level was downgraded to zero.Scientists are actively tracking 2024 YR4 to refine its trajectory and reduce uncertainties about its path. David Parnocia, a navigation engineer at NASA’s Jet Propulsion Laboratory (JPL), emphasized the importance of continued observation: “We continue to observe what we need to do and reduce the uncertainty of the position in 2032.”
The asteroid’s elongated elliptical orbit makes it particularly challenging to predict its movements. It is expected to be observable until early April 2024 but will not return near Earth until 2028.
Preparing for the Threat
The best defense against asteroid threats is early detection and accurate tracking. Scientists have been monitoring 2024 YR4 as early January 2024, using advanced telescopes and predictive models to assess its trajectory.
While the probability of impact remains low, the potential consequences are significant. For comparison, the asteroid that caused the extinction of the dinosaurs 66 million years ago was estimated to be 10-15 kilometers wide.

Table of Contents
In December 2032, Earth could face a close encounter with Asteroid 2024 YR4, a celestial object classified as a Level 3 on the Torino Impact Hazard scale. Discovered on December 27, 2023, by the Atlas telescope, this asteroid has garnered meaningful attention due to its potential impact risk. To better understand the situation, we spoke with Dr. Elena Martinez, a leading planetary scientist specializing in near-Earth objects, to delve into the details of this event and its implications.
The Revelation and Classification of Asteroid 2024 YR4
Senior Editor: Dr. Martinez, thank you for joining us. Could you start by explaining how Asteroid 2024 YR4 was discovered and why it’s classified as a level 3 on the Torino Scale?
Dr. Elena Martinez: Absolutely. Asteroid 2024 YR4 was first detected on December 27, 2023, by the Atlas telescope, which is part of a network designed to identify possibly hazardous objects. Its classification as a Level 3 on the Torino Scale means it’s a close encounter that warrants attention. This scale, ranging from 0 to 10, evaluates both the likelihood and potential consequences of an impact. While the probability of collision is currently low—around 1%—the size of the asteroid, estimated between 40 and 100 meters, means it could cause significant regional damage if it were to hit Earth.
The Torino Scale and Its Importance
Senior editor: Can you elaborate on the Torino Scale and why a Level 3 classification is noteworthy?
Dr. Elena Martinez: Certainly. The Torino Scale is a tool used by astronomers to communicate the risk of asteroid impacts to the public and policymakers. Level 3 indicates a close encounter that requires monitoring and further analysis. It’s rare for an asteroid to reach this level; the last one to surpass it was Apophis in 2004, which briefly reached Level 4. However, subsequent observations ruled out any immediate threat from Apophis.For 2024 YR4,the classification underscores the need for continued observation to refine its trajectory and assess the risk accurately.
Tracking and Predicting the Path of 2024 YR4
Senior Editor: How are scientists tracking this asteroid, and what challenges does its orbit present?
Dr. Elena Martinez: Tracking 2024 YR4 involves using advanced telescopes and predictive models to monitor its position and movement. However,its elongated elliptical orbit makes it particularly challenging to predict with complete certainty. Currently,the asteroid is about 45 million kilometers from Earth and will remain observable until early April 2024.It won’t return near earth until 2028, giving us a window to gather more data. As David Parnocia,a navigation engineer at NASA’s Jet propulsion Laboratory,noted,reducing the uncertainty of its position in 2032 is crucial.
Preparing for Potential Impact Scenarios
Senior Editor: What steps are being taken to prepare for the possibility of an impact in 2032?
Dr. Elena Martinez: The best defense against asteroid threats is early detection and accurate tracking. Scientists are actively monitoring 2024 YR4 to refine its trajectory and assess any potential risks. While the probability of impact remains low, the consequences could be significant, especially given its size. For context, an asteroid of this magnitude strikes Earth roughly once every thousand years. However, unlike the dinosaur-extinction event caused by a 10-15 kilometer-wide asteroid, 2024 YR4 is much smaller. Efforts are ongoing to develop mitigation strategies, such as deflection missions, should the risk increase in the future.
Final Thoughts and public Awareness
Senior Editor: What message would you like to convey to the public about this situation?
Dr. Elena Martinez: I’d like to reassure the public that while 2024 YR4 is being closely monitored, the risk of impact remains low. Organizations like NASA and the European Space Agency (ESA) are working diligently to safeguard our planet.Staying informed and supporting planetary defense initiatives are key.

Conclusion
Our conversation with Dr.Elena Martinez highlights the importance of continued observation and preparedness as Earth approaches its 2032 encounter with Asteroid 2024 YR4.While the risk of impact is minimal, the efforts of scientists and space agencies ensure that we remain vigilant in protecting our planet from potential asteroid threats.
