Easy. It’s a 10 minute distraction for a child over 9. I bought this for my 6 year old (loves magnets, snap circuits, legos, etc). This was fun and worth the price at $17.00. He picks it up every once in a while but I wouldn’t say this is is a learning toy so much as an experimental toy- if that makes sense.

Is the orbit of each planet accurate?

No! There is nothing even remotely accurate about this model. Save your $10, what a waste of money.

Are the batteries secured with a screw or could a kid get to them?

The batteries are secured with a screw!

What is the order to the steel posts?

No directions with this kit. You have to size them so they can rotate around each other. Had I known how frustrating this thing was I would have opted for a more expensive and slightly larger model. Hindsight is great. This kit isn’t.
