Kepler Orbit

In a freehand experiment, we could simply make a train move on a circle around the lamp. Strictly speaking, however, they move on Keplerian paths, i.e. on ellipses.

The ellipticity of the large planets of our solar system is so small that we would not be able to see them – even more so in this miniaturization. That’s why I took the scale of one of the big planets (Mars) and a typical planetoid of the Hilda group as a template for my model.

technical drawing, published in German: “Plattenmaß” means “measure/ size of the plate”, “Bahn” means “orbit”, “Rand” means “edge”; “AE” is German for “AU=astronomical unit”, “Periheldistanz” is “distance to perihelion”.
