Solar System model

This unique model consists of 16 cards: for the Sun, the planets, the Moon, asteroids, comets, the Voyagers and "ice dwarfs". They are in fact a concise encyclopedia of the Solar System! But more importantly it is a scale model (scale 1:100 billion). They provide, when completely placed, the best possible representation of the distances within our own Solar System and the emptiness of space. The complete model when placed up to Pluto is 194 feet/59 m long. There are English versions for the US (with inches and feet) and with metric units.
