The armillary sphere (also known as the 'world machine') is a complex mechanical device used to represent the movement of astronomical bodies. The positions of the planets, the sun, and the moon can be set for any location on Earth. Times and solar positions can be read, as well as sunrise and sunset times. The armillary sphere is excellent for understanding seasons and moon phases - perfect as an explanation for both young and old. In addition to the assembly instructions, the kit also includes a user manual that provides an impression of the possibilities of the armillary sphere. Easy assembly: All parts can be easily pushed out and assembled directly. The required wood glue is included.
