Celestial globe
A sphere on which the stars, constellations, and various astronomical circles are drawn. Celestial globes probably predate terrestrial globes. They are usually mounted in harnesses that allow them to rotate and be tilted to different latitudes.
Planetarium
A geocentric model of the solar system that shows the positions of the sun, moon, and planets as viewed from the earth at various times. The positions of the heavenly bodies may be indicated by individual dials, as with the Antikythera mechanism, or through the relative positions of small spheres representing the bodies, as with Archimedes' planetarium. Modern planetaria project images of the heavenly bodies onto a large hemisphere in whose interior observers are situated.
Orrery
A heliocentric model of the solar system in which the planets move about a stationary sun through a clockwork mechanism. Complicated ones can also show the motions of the moons around the various planets and the motion of the rings of Saturn. Named in honor of Charles Boyle, the fourth earl of Orrery, who purchased one of the first such devices built by John Rowley in the early eighteenth century.
Armillary sphere
A skeletal sphere formed from circular bands that denote the celestial equator, ecliptic, tropics, and arctic and antarctic circles. Usually a ball representing the earth is placed in its center. It is used to demonstrate the motion of the stars about the earth.
