The Sun is located at the school campus of Toijalan Yhteiskoulu in Toijala district.
Akaa Solar System Scale Model was built in 2017 by amateur astronomer Kari-Pekka Arola.
The current location (140 AU) of the Voyager 1 spacecraft in relation to the Solar System is also presented in the scale model (as the most distant man-made spacecraft) and the concrete pillar representing its location is at the center of the neighbouring town Viiala, approximately 7 km away from the Sun.
This ground distance takes it in the middle of Australia and near the famous Ayers Rock / Uluru.
