3I/ATLAS and the Push Near the Sun

3I/ATLAS is a comet from another star system, found on 1 July 2025 by the ATLAS survey telescope at Rio Hurtado, Chile. In July 2025 Avi Loeb and two colleagues asked whether it could be technology, citing its path past three planets and a possible push of its own. This is the record of that push: the claim, the measurements made since, and what is still open.
