Planetarium, Helios
Helios is a mechanical planetarium that models the Solar System with Mercury, Venus, Earth (with moon), Mars, Jupiter and Saturn in correct relative orbital speeds. The speed can be adjusted continuously – forwards and backwards – so that phenomena such as the retrograde motion of Mars can be clearly demonstrated. The removable dome shows the northern starry sky, and a separate 100 mm globe of the Earth is included for seasons, day and moon phases.

Solar System model
Three-dimensional model of our solar system with the 8 planets.
The model is suitable for giving students an understanding of size ratios, distances, colors and speed when the planets revolve around the Sun.
With the model, you can easily explain why some planets are only visible for part of the year.SKU: FR-560021
