As regards the question in your final paragraph, close votes happen when a question is outside the site topic as described in the Help Centre:

What topics can I ask about here?

 

Space Exploration is primarily about spacecraft, how to send them to space, and their functions there. Specifically, questions on these topics are encouraged:

• Space exploration
• Satellite design and operation
• Systems with potential use in space
• Scientific discoveries made by space probes

Questions on these topics (and many others) are not on topic here:

• The study of exosolar objects, except as they relate to space travel.
• Physical sciences, such as geology, astronomy, meteorology, except as they relate to spacecraft and space exploration.

So while the moving planets question is interesting, it doesn't fit on this site (which is about exploration) but it may have a home on Physics (as long as its core is around physics) or Worldbuilding (if the core question is around how this would be done in a novel, or an imagined universe etc)
