Comprehensive Summary of Asteroid 2024 YR4
asteroid 2024 YR4 is a near-Earth asteroid estimated to be between 130 to 300 feet (40 to 90 meters) in width.As of 2025, there is a very small chance of it impacting Earth on December 22, 2032, with NASA estimating the probability at around 1.2%. This estimate is consistent with independent assessments by ESA’s Near-Earth Object Coordination Center (NEOCC) and NEODyS.
the International Asteroid Warning Network (IAWN) is actively coordinating global observations of 2024 YR4, which is larger than 10 meters and has an impact probability greater than 1%. ESA has published a Close Approach Fact Sheet for the asteroid.
While the current risk is low, it could change with new data and improved calculations. In the past,asteroids like Apophis (99942) initially posed significant threats but were later found to have no impact risk after further analysis. If the risk for 2024 YR4 were to increase, authorities would take necessary precautions and warnings.
Key Points:
- Asteroid 2024 YR4: 130-300 feet wide, potential Earth impact on December 22, 2032.
- Current impact probability: Approximately 1.2% (NASA, ESA, NEODyS).
- IAWN and ESA are actively monitoring and coordinating observations.
- Risk can change with new data; past examples include Apophis.
- Authorities would take precautions if the risk increases.

The potential for asteroids to collide with Earth has long captivated public imagination. Recently,near-Earth asteroid 2024 YR4 has gained attention due to a small but non-zero chance of impacting our planet in 2032. Today we speak with Dr. Emily Carter, an expert in asteroid dynamics, to learn more about 2024 YR4 and the measures being taken to assess and mitigate any potential risks.
Understanding Asteroid 2024 YR4
Senior Editor: Dr. Carter,for our readers unfamiliar with the topic,can you provide a brief overview of asteroid 2024 YR4?
Dr. Carter: Certainly. 2024 YR4 is a near-Earth asteroid, estimated to be between 130 and 300 feet in diameter. It was discovered relatively recently and is currently being actively tracked by astronomers worldwide.
Current Impact Probability and Monitoring Efforts
Senior Editor: NASA has estimated the probability of 2024 YR4 impacting Earth on December 22, 2032, to be around 1.2%. Can you elaborate on how this probability is determined, and what factors could influence it?
dr. Carter: The impact probability is calculated based on a complex set of data points including the asteroid’s size, trajectory, and orbit.Elegant computer models are used to simulate it’s future path. As we gather more observational data, our understanding of its trajectory becomes more precise, and the impact probability can be refined.
Senior Editor: Are there any international organizations or initiatives involved in monitoring 2024 YR4?
Dr. Carter: Absolutely. The International Asteroid Warning Network (IAWN) is playing a crucial role, coordinating global observations and data sharing. ESA’s Near-earth Object Coordination Center (NEOCC) and the NEODyS project are also actively involved in tracking and analyzing 2024 YR4.
The Dynamic Nature of Asteroid Risk
Senior Editor: Given the nature of space,are there examples of asteroids substantially changing trajectory or risk level over time?
Dr. Carter: Yes, there are! A notable example is asteroid 99942 Apophis, which initially had a higher perceived risk of impact. Thanks to continued observations and improved calculations, scientists were able to rule out a collision with Earth.
Preparing for Potential Impacts
Senior Editor: What steps would be taken if the risk of 2024 YR4 impacting Earth were to increase?
Dr.Carter: If the probability of impact were to rise significantly, international authorities would activate established protocols.This could involve launching dedicated observation missions, developing potential deflection strategies, and issuing public warnings.
This interview with Dr. Carter underscores the importance of continuous asteroid monitoring and research.While the risk posed by 2024 YR4 remains relatively low, it serves as a reminder of the need for international collaboration and technological advancements to ensure the safety of our planet.
