Solar System

I have added the following: 

1. Mercury
2. Venus
3. Mars 

Each with material, position and rotation which roughly approximate the solar system (rotation anti-clockwise except Venus, distance from the sun, size relative to earth, etc). I also record the sound of each planet from YouTube and converted into the aif files, put them into the sound folder, then embedded into each planet.
