This is a model of all Solar System planets and Pluto. The base has a radius corresponding to the radius of the Sun. Everything is to scale.

This was designed for the UTSC Solar Walk, an installation on the UTSC Scarborough campus. The long axis should be 4.9cm for the model to be the same scale as the Solar Walk Installation. More information is available at http://solarwalk.utsc.utoronto.ca
