Illuminated Sun, Earth, and Moon Orbital Model

This three-dimensional orbital model demonstrates the changing positions of the Earth, Sun, and Moon, illustrating the science behind seasons, lunar phases, eclipses, and tides. The model features a 5.9-inch diameter sun, a 4-inch diameter earth, and a 1-inch diameter moon, all mounted on metal rods that allow manual repositioning. A 12V bulb inside the sun demonstrates the effect of sunlight on the Earth and Moon, showing how the tilt of Earth's axis creates seasonal variation as the planet orbits. The sturdy base is labeled with each month and the seasons of both hemispheres. The model stands 12.25 inches tall, 16.25 inches wide, and 4.75 inches long. Requires two AA batteries (not included). A comprehensive experiment guide with three activities, worksheets, and Solstice and Equinox charts is included.
