Abstract
Abstract An apparatus for simulating a large scale, rotating representation of the solar system inner planets and the Sun is described, comprising a series of moving and stationary concentric rings arranged about a pedestal, above which is a highly reflective globe representing the Sun supported on a column of high velocity air. Above each of the moving rings, and rotating with the rings, are globes representing the inner planets Mercury, Venus and the Earth, each planet being supported on a column of high velocity air. The Earth representation also has a Moon globe that rotates about it on a column of air. The entire top surface of the rings, moving and stationary, is painted dark blue, with plentiful representations of twinkling `stars` scattered about the surface. The apparatus is large, and is intended to be used as an educational tool in museums and the like, or be a large public display, or be combined with clocks.
