Several readers noticed something funny in the USA Today caption for the hexagon photo:

A bizarre six-sided hexagon feature encircles the entire north pole of Saturn. The hexagon is nearly 15,000 miles (25,000 kilometers) across.

Me:Uh, wouldn’t it be weirder if it were, say, a five sided hexagon? Or maybe a nine-sided hexagon? Or for that matter, six-sided square?
