Dione scaled one in ten million

This model was rendered using MATLAB R2016a on the ICQ model of the PSI made by Robert Gaskell from the data of the Cassini mission. It's scaled to 1 in 107 or one in ten million. This model is about 11cm in diameter. On this scale the Moon is a basketball and Mars' moons Phobos and Deimos are 2 and 1 mm respectively.

The file's names explained: name_1_x_10_y.stl is 1 : x* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million. 

S4 Dione

Dione is similar in size with other Saturn's moon Tethys. Like Tethys with Mimas, Dione is in orbital resonance with Enceladus, which share the characteristic of a subsurface ocean, probably sustained by the heat produced from that resonance. Dione has two co-orbital moons like Tethys: Helene and Polydeuces.

• Type: Satellite 
• Orbit: Saturn. Coorbital with Helene and Polydeuces 
• Orbital period: 2.736 d. 
• Composition: Icy body. Subsurface ocean.
• Density: 1.478 g/cm3. 
• Dimensions: 1128.8 km × 1122.6 km × 1119.2 km. 
• Model scale: 1:2x107 (22cm) 1:1x107 (11cm) 1:4x106 (5cm)
