A terrestrial globe, about 3 inches in diameter, showing basic geography, though not updated frequently due to its educational focus on celestial mechanics. A central yellow sphere represents the Sun
Smaller black-and-white painted spheres for the Moon and Venus, mounted on metal rods revolving around the Sun.
A maroon or black Bakelite arm with an embedded compass (glass and arrow are intact in excellent condition) and a zodiac dial on the base, printed with seasons, zodiac signs, and months.
In excellent condition and fully operational, this 1960 model exhibits minimal wear, intact chains with no significant oxidation, and a functioning gear system that allows for the smooth rotation of the celestial bodies. The bodies' colors remain bright, legible, and intact, with no major damage. All original parts, including the chain and compass, are present.
This planetarium is a collectible item, valued by globe, scientific instrument, and astronomy enthusiasts for its mechanical intricacy and historical significance.
