Pajamäki Solar System Scale Model

Its scale is 1:1 000 000 000, i.e. one to one billion, so that 1 millimeter in the model corresponds to 1 000 kilometers in the actual Solar System.

The model was designed by the amateur astronomer Leo Sulamaa, who has had his own observatory in Pajamäki.

The diameter of the Earth is in reality 12 760 kilometers, but in the scale model it is only just a little over a centimeter.

Due to vandalism, the Earth and the Moon in the scale model differ from the planets, they are presented as holes in a steel plate.
