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.
