The International Asteroid Warning Network (IAWN) recently announced a campaign to study the intriguing interstellar object, 3I/ATLAS. This initiative aims to improve our ability to detect and monitor potentially hazardous asteroids.
3I/ATLAS is unique and the first interstellar object targeted by IAWN’s global efforts. For context, the object will reach solar conjunction with Earth on October 21, 2025. According to IAWN, comets like 3I/ATLAS bring unique challenges, especially in predicting their paths due to their complex structures, which can confuse measurements.
The campaign will run from November 27, 2025, to January 27, 2026, and will include workshops for astronomers focusing on better astrometric techniques for comet observations. Registration for the workshops closes on November 7.
In a notable twist, this announcement follows a White Paper I submitted to the United Nations on September 30, advocating for global collaboration to study interstellar objects. Tracking and understanding such flotsam in our cosmic neighborhood is crucial, particularly since they may pose unseen threats, including potential alien technology. Events with small probabilities but massive stakes should definitely be on our radar.
3I/ATLAS displays some peculiar characteristics, giving it a score of 4 out of 10 on the Loeb Scale, which suggests a possible technological origin. Here are some standout qualities:
- Its trajectory is aligned with the ecliptic plane of the solar system, with a mere 0.2% likelihood of being a random occurrence.
- In mid-2025, it emitted a sunward jet, a signature not typical for comets, implying a unique composition.
- The object’s nucleus is significantly more massive than both 1I/`Oumuamua and 2I/Borisov, with surprising motion patterns.
- Its timing led to close approaches to multiple planets without being visible from Earth.
- The gases around 3I/ATLAS contain unusual amounts of nickel, suggesting some artificial processes.
Overall, these characteristics yield a cumulative chance of occurrence that’s incredibly small—less than one in ten quadrillion. This rarity emphasizes the importance of observing 3I/ATLAS closely.
Unfortunately, we currently lack spacecraft capable of intercepting it for direct study. Research indicates that NASA’s Juno spacecraft could have been positioned to meet 3I/ATLAS if it had sufficient fuel, making early detection crucial for future missions.
The most telling sign of 3I/ATLAS’s technology would appear near solar conjunction, likely around October 29, 2025. If it behaves like a mothership, it might deploy smaller probes that could one day reach Earth.
3I/ATLAS will be closest to Earth on December 19, 2025. As new information emerges, we may finally learn about our cosmic companion, igniting a new chapter in human understanding of the universe.
