A working model of the planetary system with a 'Star dome' making it a versatile aid for teaching basic astronomy
The planetarium comprises a circular base on which the model planets revolve around the Sun at their correct relative speeds
The upper edge of the base has a calendar and a degree scale for setting the planetary positions
The star dome is of the northern hemisphere
Supplied with teaching manual covering history, the Sun, planets, comets and space exploration as well as useful tips for demonstration
Complete with all accessories, and a 240V mains power unit fitted with double insulation and thermal cut‐out for overload protection,
It is supplied with a star dome for the northern hemisphere
This orrery is suitable from Key Stage 2 to University levels of education
The model enables the study of the following topics: The Planets in their orbits (length of a year, inferior and superior planets)
The phases of Venus
The Moon and its phases (external light source required)
Eclipse basics
Time ‐ solar, sidereal and G
M
T
The ecliptic and the Zodiacal constellations
How the planets appear to move against the night sky
Use of the Helios outside at night ‐ where should the stars appear in the sky?With the large Earth and Moon accessories that are included, you can also watch as the Earth rotates on its axis while the Moon orbits it every 29.5 'days'
Using an external light source (torch, projector), the larger size of Earth and Moon enables you to demonstrate the following events much more clearly: Day and night
Shadows and the seasons
The Moon's month, phases and eclipses
The Pole Star, circumpolar stars and a nocturnal
The Moon and stars from different positions on Earth
