Semi-major axis

Summary

  • From a page move: This is a redirect from a page that has been moved (renamed). This page was kept as a redirect to avoid breaking links, both internal and external, that may have been made to the old page name.
  • To a related topic: This is a redirect to an article about a similar topic.
    • Redirects from related topics are different than redirects from related words, because a related topic is more likely to warrant a full and detailed description in the target article. If this redirect's subject is notable, then also tag it with {{R with possibilities}} and {{R printworthy}}.
  • From a printworthy page title: This is a redirect from a title that would be helpful in a printed or CD/DVD version of Wikipedia. See Wikipedia:Printability for more helpful information.
