that might need some correction...

Wikipedia states: The Sun is the star at the center of the Solar System.

According to some articles on the web, other stars can be suns as well, if they contain a planetary system.

In common language however "the sun" is typically our star. "a sun" might be other stars as well.

I think most people dont understand and think about the difference and thus think a star is a sun.
