Vintage circa mid-1970s Helios Planetarium electric motorized orrery with star dome, measuring approximately 13″ in diameter, complete with its original manual and planet models. In very good to fine condition, with pages in the manual separating from the binding. The planetarium appears to be functional when plugged in: the sun can be illuminated and the planets rotate in either direction, with adjustable speed; the moon correctly orbits Earth.
