A fully electric, highly accurate model of the planetary system. The planets from Mercury to Saturn rotate around the sun at their correct relative speeds while the moon orbits the earth. Planets can be correctly positioned according to a calendar and degree scale for any month and year. The star dome shows the stars and constellations visible at night for any given time of year. Change the set up to the earth-centered model to study additional topics including eclipses, phases of the moon and tides.
Supplied with a comprehensive teaching manual covering all common astronomy topics and useful tips for demonstrations. Complete with all accessories, a 240V mains power unit fitted with double insulation and thermal cut-out for overload protection. Can also operate with 4 x 1.5VD batteries (not supplied).
