Built in 1998, the Astronomy Park conveys an impression of our solar system's size. At its centre is an equatorial ball-and-ring sun dial with dual functions. Firstly it is an astronomical chronometer that tells true local time, seasonal changes and the noon hour of the earth's major cities. Secondly it represents the size of our sun on a scale of 1:10^9 metres (= 1.39 metres).
