This program simulates the inner solar system: Mercury, Venus, Earth, and Mars. Choose your own notes for each planet or set them to drums instead!

To listen to the outer solar system instead, set the periods of Jupiter to 0.29, Saturn to 0.719, Uranus to 2.046, and Neptune to 4.

If you miss Pluto you can add it with a period of 6.058. Set their colors and sizes to resemble the actual planets and choose any notes or drums you like!
