| Trippensee® Planetariums –
Classic Orreries The Trippensee Planetarium (#EL- 400) and the Motorized Trippensee® Planetarium (EL-500)are high-quality orreries designed to demonstrate the motion of the Earth, Moon, Venus, and Sun. Both models perform the same functions; the difference is that the motorized version features a spring wire connection to the red arm, which automatically moves the planetary system in motion. Durable and reliable, these planetariums are gear- and chain-driven, ensuring exceptionally long life and smooth operation. The Earth maintains its 23.5° axial tilt while rotating on its axis and revolving around the Sun. The Moon orbits the Earth while always keeping one face toward it, and Venus revolves around the Sun, with the option to position it by hand to show its phases and role as the morning or evening star. Demonstrated Phenomena: * Phases of the Moon * Solar and lunar eclipses * Causes of night and day * Seasonal changes across Earth * Winter and summer explained * Solstices and equinoxes * Earth’s axis and alignment with the North Star * Tides and their causes * Earth’s equator, latitude, longitude, and meridians For over 90 years, Trippensee has produced portable desktop planetariums that provide clear visual demonstrations of the solar system in motion. These models are perfect for classrooms, libraries, and home learning—making astronomy accessible to both children and adults. Special Note: Earth on the globe is represented with dark blue or black oceans. |
