"seems the sun have a "moon""
---------
Are you referring to the fact that Venus shows phases (like Mercury ... since both are closer to the Sun).
Galileo's observations of Venus's phases was proof for him that the Earth centred "Universe" was not correct and that the Su-centred model was true (of course he had no idea then that even this wasn't quite true as the Sun wasn't really the centre of the cosmos but just this particular system of planets).
