A five year old question Do the planets really orbit the Sun? which received 117 up votes and 2 down votes has now been closed by 5 users as off-topic.
I've argued that
To explore the solar system we need to know where objects in the solar system are in order to determine proper trajectories. To do that we need to appreciate the details of how solar system objects move and that understanding includes the fact that the inner planets orbit mostly around the Sun, but the Sun and the inner planets also move in a small but crazy way about the barycenter of the Sun and the outer planets. Without this understanding interplanetary exploration is impossible.
The help page can't cover edge cases like that in such a short space. Instead we can trust the community. So I'm voting to re-open because 115 > 5.
I feel that this question, and its closing is an example of at least some of the following:
- Questions can be on-topic in multiple sites, on-topic elsewhere does not mean off-topic here.
- The help center is a preliminary guideline but we need to take the community's views into account, as seen in its participation on the question and the number of related questions.
- The "tyranny of five" should be used with extreme caution; closing affects everyone by blocking everyone from posting further answers.
- That orbits are n-body and not Keplerian is a constant theme of Q&A here as it is the main point in answers to this question.
