About This Product
Once the hub is fixed to a beam or reinforced ceiling grid, the arms go in order from Mercury nearest the Sun to Neptune farthest out, and each planet snaps on and is set to its distance. Turning the arms by hand shows that outer planets have longer orbits, lets the class set up alignments, and gives a starting point for scale and distance calculations from the guidebook.
Frequently Asked Questions
Is the Hanging Solar System STEM Lab motorised?
No. It is moved by hand, so orbits can be stopped, reversed or set to particular alignments during a lesson.
