Among those depicted are the orbits of the 9 planets and their relative distances from the sun, the orbits of halleys comet and enckes comet, a circle representing the solar disk on which is superimposed 9 smaller circles, demonstrating the relative size of each of the planets, the four largest of the minor planets (asteroids) compared in size to the earths moon, the visual appearance of halleys and donatis comets, the apparent phases of venus, and the astronomical symbols for the planets.
