4M Green Science Solar System Planetarium: The Planets in Motion

The 4M Green Science Solar System Planetarium is a build-it-yourself model kit that brings the planets to life using a solar and battery hybrid-powered motor. Children assemble the full model themselves, then watch the planets move around a central sun, powered either by sunlight or batteries.

How It Helps

Building the planetarium takes children through each stage of assembly, including basic circuit building, before the completed model is ready to demonstrate planetary movement. Suitable for children aged 5 and over, the kit includes educational fun facts about each planet, adding a knowledge-building element alongside the hands-on build.

• Demonstrates planetary movement using a working, motor-driven model
• Solar and battery hybrid power shows two different ways to run the same motor
• Encourages hands-on circuit building and step-by-step assembly
• Includes educational fun facts about each planet to support learning alongside the build
• Comprehensive kit with all components included for a complete build

Building and running a working model gives children a memorable, hands-on way to understand how the planets orbit the sun, rather than relying on diagrams alone.

Whether used for a school project, science fair, or a home activity, the Solar System Planetarium offers an engaging way to bring astronomy and renewable energy together.

• Solar and battery hybrid-powered motor: drives the planetary movement using sunlight or batteries
• Comprehensive kit with all components included for a complete build
• Educational fun facts about each planet included alongside the model
• Suitable for children from 5 years and up
• Assembled model measures approximately 37.0cm (W) x 15.5cm (H) x 32.0cm (L)
• Brand: 4M, from the Green Science range
• Barcode: 4893156034168

• A genuinely moving model. The planets orbit using a working, motor-driven mechanism, not just a static display.
• Two ways to power it. The solar and battery hybrid motor shows how the same model can run on sunlight or batteries.
• Great for projects. Well suited to school projects, science fairs, or a hands-on activity at home.
• Trusted STEM brand. Part of the well-established 4M Green Science range, known for accessible, curriculum-friendly science kits.

What's in the Box
