The allure of astronomy lies in its invitation to everyone to become an explorer of the universe. Traditional astronomy education often remains at the level of passively receiving information, while modern exhibition technology creates an experiential path of active discovery. Understanding the solar system is not just about memorizing planet names, but about establishing a cognitive understanding of the dynamic relationships between them—the scientific connections between size comparisons, orbital characteristics, and material composition. The "Eight Planets" exhibit is designed precisely for active exploration. A precisely scaled model suspended above first establishes a visual anchor, allowing you to intuitively grasp the actual scale of Earth in the universe. Then, the interactive touchscreen system hands over the initiative of exploration: you can freely click on planets of interest to learn more about their atmospheric composition and geological features; you can compare the orb
