The Lohja solar system model provides a vivid understanding of the vast scale of space. Placed within a familiar landscape, the model is easy to grasp, and the sizes of the planets become clearly tangible.

Light takes over four hours to travel from the Sun to Neptune’s orbit—the same time it would take to cycle from Lohja to Turku!

The starting information board is located at the Asema water tower, where the 32-meter-high tower represents the Sun, the center of our solar system. Hop on your bike and explore the information boards placed along the orbits of the four inner planets!
