Orbiting Solar System STEM Kit | Build a Rotating Solar System Model |
Build a colorful, mechanical, rotating model of our solar system!
The model uses a windup motor to set the planets in motion--no batteries
Explore fundamental gear mechanics and discover a special type of gear called
a planetary gear.
Great for science fair projects, you'll learn about the planets' celestial
orbits and tons of cool planetary facts.

Assembly time: 1-2 hours, Difficulty Level: Intermediate
Set the planets in motion with a flick of your wrist! Build a mechanical model
of the solar system including the sun and eight planets (also known as an
orrery), wind it up, and watch the planets revolve around the sun. Assemble
this complex machine using snap-together plastic parts to learn how the gears
and wind-up mechanism work to spin the model. Detail each planet with colorful,
realistic-looking printed planet graphics. Discover how a special type of gear
called a planetary gear is used to simulate the mesmerizing motion of the solar
system. Learn about the order of the planets, their relative sizes, their rates
of revolution around the sun, their appearance, and other planetary facts.
