This might just be me being incredibly inobservant, or the failing eyesight, but I've not noticed when you go to the system map that any of the planets are actually rotating. I'm looking at a system map now, 3 or 4 gas giants, with a bunch of moons, 4 inner planets of the solid variety. All of them, rock steady. Except the third one, which is spinning, darn it! Has this been here from the beginning?!
