The Trippensee Planetarium is a demonstration model of the movement of the earth, moon and Venus relative to each other and to the sun. It shows such phenomena as the succession of seasons, and solar and lunar eclipses. In addition to its educational objective, the tellurian is also decorative and entertaining. The original models, patented in 1908, have maple arms and central standards. Those produced around the second quarter of the 20th century have ebonized arms and central standards. Models made after World War II models are of Bakelite or plastic.

Our models are sold in working condition, however, we are frequently asked about replacement parts or repair of antique and vintage tellurians:
• Spare Parts: Trippensee is still in business, now owned by Science First. We do not sell spare parts, but the company does. Replacement parts, such as chains and gears, are often available for their current line as well as for older models. For more information, contact them.
• Repair: If you are having trouble getting the chains or gears on your planetarium to engage, you might try taking it to a local antique clock repair person.
