Geocentric Orrery: A Mechanical Model of the Solar System

A geocentric orrery is a mechanical model that places Earth at the center. It illustrates the motions of the planets around our planet.

A geocentric orrery is a mechanical model that places Earth at the center. It illustrates the motions of the planets around our planet. The model uses gears and rotating arms to show orbital paths. It serves as an educational tool for visualizing celestial mechanics. The article likely describes its construction and historical context. Such models demonstrate the geocentric view that dominated earlier astronomy. They help learners grasp the relative positions of planets. The orrery remains a popular exhibit in science museums.
