Overview
- An automated candidate labeled CE2XZW2 was posted from only four observations and initially yielded a high nominal collision probability.
- Within about a day, the Center for Small Planets moved CE2XZW2 to an unconfirmed category after linking it to 3I/ATLAS, which is moving away from the planet.
- Astronomer Nikolai Zheleznov had estimated the candidate’s size at roughly 20 meters with an expected atmospheric explosion, highlighting uncertainty in first-night orbits.
- Scientists are continuing to monitor 3I/ATLAS for unusual coma behavior and reported jets, with Avi Loeb noting a lack of fine dust, while other experts say a weak or absent tail is normal as it leaves the Sun.
- The incident underscores the limits of automated survey alerts based on short arcs and the need for rapid multi-night follow-up and better coverage of sunward approach blind spots.
