Pajamäki Solar System Scale Model, Solar System scale model in Pajamäki and Elfvik, Finland.
The model extends across Helsinki and Espoo, featuring a 1.4-meter Sun atop a 20-meter pole with planets positioned according to their actual distances.
Finnish amateur astronomer Leo Sulamaa designed this astronomical educational model in 1992, introducing a scale of one millimeter to represent 1000 kilometers in space.
The scale model incorporates multilingual information panels in Finnish, Swedish, and English, enabling local residents and international visitors to learn about planetary dimensions.
Earth and its moon appear as holes in steel plates rather than traditional spherical models due to repeated acts of damage to the original structures.
At this scale, light would travel at merely 0.3 meters per second, while one light year would span 9,460 kilometers in distance.
