The kit features simple structures such as snap-fasteners and brackets, allowing children to assemble the planets and orbits independently: First, they secure the sun's base, then snap the planets into their corresponding orbits one by one, gradually building their very own solar system model. During this process, it not only hones children's fine motor skills, but also helps them grasp the logic of "planets orbiting the sun" through spatial construction — for instance, "Mercury's orbit is closest to the sun, so it has the fastest orbital speed" and "Saturn's orbit is in the outer circle, placing it further back." This turns previously obscure astronomical laws into something clear and easy to understand through hands-on practice.

Fun Assembly + Thinking Exercise: Realize the assembly of planets and orbits through simple structures such as snap-fit connectors and supports. Children build their "exclusive solar system" with their own hands, which not only exercises practical ability, but also helps them understand the operating logic of planets (such as orbital revolution relationships) during the spatial construction, making abstract astronomical concepts concrete and perceivable.
