SIDEREAL
You keep a brass orrery. A patron names the bodies and the hour; you cannot move the sky, only the gearing that drives each arm. Fit a pair of wheels to every spindle — a bigger driven wheel turns the arm slower — read what the machine predicts, and let it run until they come round to the same bearing.

An interactive 3D universe sandbox of the real solar system.

Tap any body to inspect it, scrub through time, and watch Eris crawl at aphelion on its wildly eccentric orbit.
