Motion of the Sun, Earth and Moon
★Exhibit Content: Popular science on the movement of the Sun-Earth-Moon system and solar eclipses, lunar eclipses, and lunar phase changes ★Interaction: Electromechanical interaction ★Operation: Rotate the circular platform; the cantilever mechanism drives the Earth and Moon models to move synchronously. Observe the positional changes of the Sun, Earth, and Moon to intuitively understand the conditions for solar and lunar eclipses. ★Exhibit Description: The exhibit consists of a vertical display stand, cantilever transmission bracket, luminous Sun model, Earth model, Moon model, and electromechanical transmission device. It is a recommended exhibit from KexMall. The exhibit uses a three-dimensional cantilever mechanical linkage structure to simulate the spatial orbits of the Sun, Earth, and Moon; the luminous Sun model continuously provides a light source, the Earth revolves around the Sun, and the Moon revolves around the Earth synchronously, dynamically demonstrating the changes in their spatial positions and intuitively showing the formation processes of solar eclipses, lunar eclipses, and lunar phase changes, helping visitors understand the celestial motion laws of the Sun-Earth-Moon system. ★Scientific Principle: This exhibit is based on the orbital motions of the Sun-Earth-Moon system and the principles of light and shadow projection. The Moon revolves around the Earth, and the Earth revolves around the Sun; when the Moon moves between the Sun and the Earth and the three are approximately in a straight line, the Moon blocks sunlight, causing a solar eclipse on the Earth's surface; when the Earth moves between the Sun and the Moon and the three are approximately in a straight line, the Earth blocks sunlight, and the Moon enters the Earth's umbra, causing a lunar eclipse; the lunar phase changes occur because the hemisphere of the Moon illuminated by the Sun, during its orbit, has a periodically changing illuminated area as observed from Earth.
