Abstract: An orrery for teaching a user about the solar system. The orrery includes a generally hollow sphere and has an outer surface and an inner surface. The sphere is generally transparent. Each of plurality of rings has consecutively descending smaller diameter from a largest ring to a smallest ring. A plurality of pair of couplers couple the rings to each other and couple the largest ring to the inner surface of the sphere such that the rings are positioned within each other in order of descending lengths of diameters and are concentric. Each of a plurality of globes represents a planet of the solar system and each is attached to one of the rings such that the globes are extendable along the rings. An orb, being generally coaxial with the smallest ring, is attached to the smallest ring by a plurality of fasteners. The orb represents the sun.
