Antique Solar System Model
This set includes every one of the planets, and are set in scale. They are, starting from the bottom row, in the order Mercury, Venus, Earth, and Mars. And on the second row, Jupiter, Saturn, Uranus, and Neptune. And in the top center, the Sun. Both rings rotate, and the Sun is connected to the seccond ring. I think this would make a terrific set because of the afformentioned posability, and because of its accuracy. So it would make a great set, even though I just built it for fun.
