One of my simulation software projects for a class last century was to try and recreate the slight “wobble” stars have from suspected orbiting planet pulling on them. The simulation proved they could but it took a fairly large planet in a closish orbit. Planet finding techniques have improved considerably. One problem I remember having was Setting the initial state so the planets didn’t just slide off my coordinate system with a constant velocity.
