Planetary Rhythms, set of 10 cards

Planetary Rhythms

A set of 10 postcards

We would like to show how exciting and aesthetic the seemingly simple movements of the planets of our solar system are at first glance.
The planet movement pictures show the forms created by the relative movement of 2 different planets. In a particular rhythm, connecting lines between two planets are drawn over a defined period of time.
The lines have a color gradient corresponding to the planet color. The point of view from where the phenomenon is observed, e.g. Sun (heliocentric) or Earth (geocentric) has an influence on the resulting image.
The calculations of the planetary positions follow a method that NASA also uses to control satellites.
