proportional solar system
Planetary orbits are approximately elliptical with the sun as the center, the orbital spacing is scaled proportionally (e. g., the position of the asteroid belt between Mars and Jupiter is accurate), the orbital inclination and direction of revolution (mostly anterograde) are consistent with scientific observations, and some models may contain details of the planetary rotation direction (e. g., Venus reverse rotation).
