Inspired by several email conversations with IAAA members, this is my interpretation of the classic size/scale diagram of our Solar System.
The upper and lower thirds illustrate the physical sizes of our planets, from Mercury to Neptune, and including Pluto and Charon. The outline of our Sun is on the left side as a size reference.
The middle portion illustrates the distances between the planets. Again, the sun is the reference. Here sizes are only approximate, but relative distances are to scale.
Principal moons of all planets are also shown to size scale, not distance.
The bottom right has a locator map of our approximate location within the Milky Way Galaxy.
The big green button activates a Sonification. The sound of a grand piano represents the planets. The bigger the planet, the lower the pitch. The principal moons are represented by a String Synth. The background drone is a tenor sax, dropped an octave. This sound is generated from a brightness cross-section of our Sun.
The substrate is MDF backed by plywood. Multiple layers of epoxy colour and protect the piece. Colours are my interpretation based on several NASA images. The frame is Spalted Maple, and includes the electronics for the Sonification.
