This JPL release attributes a 2–16 km comet diameter to Meech’s team, corresponding to the 1–8 km radius relayed in the Siraj–Loeb paper. It does not establish a unique size. Interstellar confirmation was pending when the release appeared; its forecasts are historical. Ordinary cometary appearance and public institutional collaboration are described.
Received publisher text; underlying originals remain gapsSiraj and Loeb argue that a roughly kilometer-scale Borisov nucleus better matches an assumed ordinary Oort-cloud mass budget. An eight-kilometer alternative produces substantial tension with that benchmark, without independently disproving the larger size. Their figure uses four points for three object families, including two alternative Borisov radii. Sparse Poisson bounds do not capture every observing or population uncertainty. This is a conditional argument using reported observations, not a new measurement campaign or artificial-origin finding.
Received written text and native layouts; originals and interpretation gapsLoeb models a population mass budget for 3I/ATLAS and offers ordinary cometary-core or rarer-population alternatives. Technological design is conditional speculation; albedo, size, selection and reservoir assumptions remain explicit, with no artificial-origin detection or independent model validation.
