The planets in realistic proportions are accommodated by a no soooo large model by the sun. Place the models in the garden or clue it to a rope. The proportional distances to the sun will be:
1. Mercury: 6 cm
2. Venus: 10 cm
3. Earth: 15 cm
4. Mars: 24 cm
5. Jupiter: 70 cm
6. Saturn: 140 cm (!)
7. Uranus: 280 cm (!!)
8. Neptune: 450 cm (!!!)
There is no planet Pluto because it is classified as a dwarf planet and doesn't belong to the big boys anymore :(
The author marked this model as their own original creation.
