5B were amazed at the enormous scale of our solar system when we made a model of it using different sized balls and toilet paper. In the picture, you are looking at Uranus (tennis ball) back to Jupiter (basketball) and the sun (8 children holing hands in a circle). By our calculations, Neptune is 170 sheets of toilet paper from the sun whereas Earth was only about 4 sheets away (but this is still 150,000,000km)!
Just how big is the solar system?
