Anotations

Scope note:

Mechanical models of the solar system that demonstrate the movements of some or all of the planets around the sun, sometimes also of moons around their planets, in their correct relative periods, by means of an elaborate, usually clockwork, system. For the buildings housing devices used to project celestial images or for the mechanisms themselves, use "planetaria."
