For the last Venus Transit I made a to scale model of a part of the solar system, ran out of room to fit Saturn in the park though.

From memory the Sun was about 7" in radius or diameter, cannot remember. Earth was a few metres out, Jupiter was about 100m, Saturn about 200m, Pluto just shy of a km. The nearest star to us was around Malaysia.

A scale model of our Solar System. NSW

If you’re travelling in your car at 100km/hr along the Solar System Drive, you’d be “virtually” hurtling through space at a million kilometres per second - more than three times faster than the speed of light!
The Sun is over 1.39 million kilometres wide but when scaled to the size of the Anglo-Australian Telescope dome, Pluto is less than 200 kilometres away – and the size of a billiard ball!
