Setze die Planeten auf
die zugehörigen Stäbe
Nun kannst du die Planeten um die Sonne kreisen
lassen. Stecke dazu drei Finger in die Vertiefungen
und halte die die obere Gehäusehälfte mit der
anderen Hand fest. Drehe nun die Scheibe sieben
volle Umdrehungen gegen den Uhrzeigersinn und
lasse die Sonne anschließend los.
FERTIG!

You built an orrery! An orrery is a mechanical model of the
solar system (or of just the Sun, Earth, and Moon) that
shows the relative position and motion of the planets around
the Sun. However, this model only shows four orbital speeds
of the planets. In reality, each planet has its own orbital speed.
If the orrery were true to scale, it would have to have a length of
several hundred metres, given the size of the Sun in your model,
and the Earth would be smaller than the head of a pin.

Insert each planet into
the correct rod.
To make the planets orbit the sun, put your fingers into the
three circular holes on the dial and hold the upper half of
the casing with the other hand. Turn it counterclockwise up
to seven times and let go.
