The model shows the axial tilts and relative rates of spin of the Sun, 8 planets and Dwarf Planet Pluto.
Axial tilts cause the elevation of the Sun in the sky to vary throughout the year and hence give rise to seasonal variations, even on the outermost planets. The model also demonstrates the widely differing relative rates (and direction) of spin of the bodies, accurate to 1%.
The model is in five modules of similar appearance and most parts are standard; celestial bodies are represented by non-Meccano small balls or spheres. The modules are linked together and driven by a single motor.
