It might help to get some idea of the scale of the solar system if you make a model of it. Use a football as the Sun, and find or make objects the sizes shown in this diagram of the planets. For the asteroids and the comets you can use grains of sand.
Place your planets at the distances given in this table to make your scale model.

Planet

Distance from Sun in model

Mercury

10m

Venus

19m

Earth

27m

Mars

41m

Asteroids

75m

Jupiter

139m

Saturn

255m

Uranus

500m

Neptune

800m

Pluto

1km

Comets

1,000km

m means meters and km means kilometers. 1km = 1000m. You can pace out the distance to the nearer planets. It takes about two steps for each meter. The further planets are so far away you will just have to try to imagine them. Note that the distance to the comets in this model is about the same as the length of Britain.
You might like to know that in your model 1m represents 5.6 billion meters in the solar system.
