There is a limit to haw far into the future we can predict the trajectory of a comet or asteroid. It depends how well the orbit has been determined and how close it gets to any of the other big solar system bodies. Jupiter serves as a cosmic hoover by slingshot effect putting things into orbits that typically intersect with it or get flung much further out. Shoemaker Levy 9 famously suffer that fate
That insight has been formalised as a claim that the planets' orbits are chaotic over longer time scales, in such a way that the whole Solar System possesses a Lyapunov time in the range of 2~230 million years.
