See three-dimensional planet models along the way as you shuttle from Pluto at the furthest reaches of the Solar System to the Sun, which is represented by the 37-metre Anglo-Australian Telescope dome at Siding Spring Observatory.

The planets are displayed on huge billboards with the size of the planets and the distance between each billboard scaled relative to the dome – the Sun - along the five main roads that lead to Coonabarabran in regional NSW. You can also learn interesting facts about the Solar System and the unique features of each planet – did you know that it rains sulphuric acid on Venus?
