The Planets of Our Solar System to Scale: 3D printed accurate scale model of 8 planets and Earth’s moon. Wonderful detail given by the 3D printing process reproduces the belting on the gas giants. In this model: Earth (diameter = 0.80 cm) and Jupiter (diameter = 9.0 cm). This scale mode allows a direct comparison of the Earth to the Great Red Spot on Jupiter (a hurricane type storm in the Jovian clouds that is more than 500 years old). The ring system of Saturn is color printed on transparency f
