A literal reading of the bible would indicate that they aren't anything like our sun.

Very good point. Genesis says that God created the Sun, moon and stars on day 4, I believe it was. Those are distinctly separate words in Genesis, yet science believes that stars are merely different suns a great distance away.

Are the astronomers wrong? Or is Genesis not to be taken litterally?

Thus proving that a day wasn't determined by rotation relative to either the Sun or the stars.
