Yeah, let's just measure the density and composition of a comet that will be here in a few months, and with expectations that it may be releasing new gaseous formations as it gets closer, predict what will happen with those formations.

Let me just code that up real fast.

You can literally measure anything, that’s not the same as being 100% precise. That’s how it works.

The difference is compounding, unstable systems.

In much simpler form, it's similar to the "Where will this satellite in a decaying orbit land?"

The difficulty is not the approximation: the difficulty is that whether drag begins to increase at t=x or t=x+30sec (based on orientation when it first encounters atmosphere) cascades throughout the rest of the equations and dramatically changes the results.
