A walk along the planets.
During a walk along the approximately 5 kilometer long Planet Trail, you get a fascinating insight into the world of our solar system and its vast dimensions. The astronomical tour begins with the sun at Heltauer Platz, represented here as a 1.40 m high model. Along the way, you explore eight granite columns which represent the planets at a scale of 1:1 billion. The columns are distributed throughout the city so that they correspond to the distances of the respective celestial bodies from the sun at the same scale. The Planet Trail finally ends at the Harz Planetarium, which invites you to visit.
