Orbiter
- Made of superior quality polymers.
- Sturdy structure and good stability.
- A smooth Gear-driven model.
- Manually movable moon.
- Shadow hemisphere to represent night.
- Includes a detailed instruction manual.
How many days does it take the Earth to revolve around the Sun? The answer to this question and more are answered when using this gear-driven model representing the Sun, Moon and Earth and their relationships. Daylight, night, seasons, and phases of the Moon are all effectively demonstrated. Arm is 15″ long; Sun is 6″ in diameter; Earth is 4″ in diameter; moon is 1″ in diameter.
