Maybe for some stars.  Technically star S2 takes 15 1/2 years to
go around once (it's very close to the central black hole) and we
*already have* observed it in a complete orbit already.

https://en.wikipedia.org/wiki/S2_(star)

Besides, we don't have to watch a redwood tree grow from a
seedling to an old giant tree for 3000 years to know how redwood
trees grow.

>How could you possibly claim that, Odd?

We already know the laws of gravity, which predict conic
sections for orbits.

S2's orbit is an ellipse, with eccentricity 0.876.

We know it because we observed it!
