Newly Discovered Comet Is Likely Interstellar Visitor

NASA Jet Propulsion Laboratory. jpl.nasa.gov. September 12, 2019.

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.
