thanks, very clear explanation... but followup

The object we are studying might not move in the same repeatable orbitable pattern around our (0,0)... like say a comet or asteroid that is moving in a straight line out of any given orbit. So regardless of our "0,0" point - that will constantly be moving ... so a day or a week or a month later - how would that specific comet be addressed?

Thanks!
