Do you know what else you could see from Saturn?

Anyone, at least with common sense, could have made the observation that we extract the information that we along with the other planets travel around the Sun by assigning relevance to different aspects like phases for a faster moving planet or the temporary falling behind in view (direct/retrograde motion) that is easily discernible for the further out planets -

People must imagine that these observations must come with some sort of formal decorum when really they pop up out of the blue and the astronomer takes notice. Nobody pointed out before that observations from Mercury wouldn't show phases of any of the other planets while observations from Venus would show phases of Mercury but even when people seem hard to please nowadays, these things delight those who can appreciate them for their newness.
