Does Comet Swan take 11000years to fly by us again? Kajan Lakhan (talk) 14:56, 18 May 2020 (UTC)


 * The observation arc of 18-days is still too short to know for an object with such a high eccentricity. You will never know the orbital period to 5 significant figures. With long-period comets it is really the order of magnitude that we want to know, i.e. ~10 thousand years or 1+ million years. -- Kheider (talk) 15:07, 18 May 2020 (UTC)


 * It is kind of both. It took many millions coming in and will take very crudely ~11000 on the next orbit. -- Kheider (talk) 16:11, 2 June 2020 (UTC)
