Product description

Product Model:

DM405

Model Description:

The formation of the solar system began approximately 4.6 billion years ago, when a small portion of a massive molecular cloud collapsed under gravity. Most of the collapsed material accumulated at the center, forming the Sun, while the remaining material flattened into a protoplanetary disk. Planets, moons, asteroids, and other small celestial bodies in the solar system all formed from this protoplanetary disk. This model allows you to understand the movement laws and characteristics of different planets, making it an ideal gift for space enthusiasts.
