Earth-Sun-Moon System
★Exhibit Content: Popular science on the relationship between the Sun, Earth, and Moon, and solar eclipses, lunar eclipses, and lunar phase changes ★Interaction: Electromechanical interaction ★Operation: Press the start button to watch the model demonstrate the orbits of the Sun, Earth, and Moon, and learn about the natural phenomena caused by changes in their positional relationships. ★Exhibit Description: The exhibit consists of a display stand, an operating device, a three-sphere model, and a transparent protective cover. Using mechanical linkage principles, the exhibit simulates the real motion of the Sun, Earth, and Moon in space, intuitively showing their positional relationships; through the model, it recreates the orbital scene and demonstrates the causes of natural phenomena such as solar eclipses, lunar eclipses, and lunar phases, revealing the mysteries of space, and aims to help visitors understand the intrinsic connections of the Sun-Earth-Moon system. ★Scientific Principle: This exhibit is based on the celestial motions and light-shadow effects of the Sun-Earth-Moon system: The Moon revolves around the Earth while the Earth revolves around the Sun. The periodic changes in their positional relationships give rise to phenomena such as lunar phases, solar eclipses, and lunar eclipses; When the Moon moves between the Earth and the Sun, and the three are in a straight line, a solar eclipse occurs; when the Earth moves between the Sun and the Moon, and the three are in a straight line, a lunar eclipse occurs; Lunar phase changes occur because the proportion of the Moon's sunlit hemisphere visible from Earth changes as the Moon's orbital position varies.

★Exhibit Content: Popular science on the zodiac, seasonal starry skies, Earth's revolution, and the annual apparent motion of constellations ★Interaction: Electromechanical interaction ★Operation: Press the start button to watch the model demonstrate Earth's revolution around the Sun, observe the corresponding zodiac constellations at different times, and understand the causes of seasonal changes in the starry sky. ★Exhibit Description: The exhibit consists of an octagonal display stand, a circular stainless steel railing, a starry sky disk, a Sun-Earth model, and an electromechanical drive device. It is a recommended exhibit from the KexMall exhibit mall. Using mechanical linkage principles, the exhibit simulates Earth's revolution around the Sun. The disk is printed with zodiac constellation patterns and a starry sky background; visitors can intuitively observe how the constellations visible at night change as Earth moves to different positions in its orbit, demonstrating the principle of seasonal starry sky changes and helping visitors understand astronomical knowledge such as the ecliptic, the zodiac, and the annual apparent motion of constellations. ★Scientific Principle: This exhibit is based on Earth's revolution and the principle of annual apparent motion. As Earth revolves around the Sun, the direction in which observers on Earth face the universe constantly changes with the seasons; the constellations visible at night on the side facing away from the Sun also change, forming the seasonal starry sky. The ecliptic is the apparent path of the Sun on the celestial sphere, and the zodiac consists of the twelve constellations distributed along the ecliptic belt, which are star regions divided by ancient astronomical observations.
