Cycle the Solar System

York’s solar system model

The scale of our model is 575,872,239 to 1. So every 100 metres along the track corresponds to more than 57 million kilometres in space. The speed of light is about 1.16 mph, so it is easy to walk at 3 times the speed of light and to cycle at 10 times the speed of light. Every journey down the cycle track ends before it begins and every time you travel on the track you will become a little younger

Beyond Pluto the next star in our galaxy is Alpha Centauri, more than 40,680,200,000,000 km away. On our scale model this would be 70,641 km from Riccall, or about one and three quarters of the way around the Earth, perhaps near Hawaii on the second time around!

 

This table gives the real dimensions of our Solar System; the diameters of the Sun, its planets and their moons are shown along with the orbits of the planets around the Sun and the orbits of the moons around their planets. Only the bodies in red are represented on the model
