3. Which arrangement of pins provided the closest match to the orbits of planets?
pins close together
Or pins far apart

pins far apart

Explanation:

The orbit of the planets is described as an elliptical aorbite of great eccentricity and complexity. In this case, in a situation where a pin diagram would try to more accurately reproduce the orbit of the planets, it would be necessary to place these pins far from each other, as placing them too close together would decrease the eccentricity of the ellipse.
