All stars are fixed point-like, basically static coordinates, so it's more of when one object encroaches another within a few micro-degrees.
3-body problem implies crazy perturbations and chaos theory and invoking of pendulum analogies, and all that's true, but due to the magnitudes of difference between human timescales and cosmological, we know the eclipses, occults, and all other matter of quirky alignment and other miscellaneous minute for millennia to come.
