Explanation: Does the Sun change as it rotates? Yes, and the changes can vary from subtle to dramatic. In the above time-lapse sequences, our Sun -- as imaged by NASA's Solar Dynamics Observatory -- is shown rotating though the entire month of January. In the large image on the left, the solar chromosphere is depicted in ultraviolet light, while the smaller and lighter image to its upper right simultaneously shows the more familiar solar photosphere in visible light. The rest of the inset six Sun images highlight X-ray emission by relatively rare iron atoms located at different heights of the corona, all false-colored to accentuate differences. The Sun takes just under a month to rotate completely -- rotating fastest at the equator. A large and active sunspot region rotates into view soon after the video starts. Subtle effects include changes in surface texture and the shapes of active regions. Dramatic effects include numerous flashes in active regions, and fluttering and erupting prominences visible all around the Sun's edge. This year our Sun is near its Solar maximum activity of its 11-year magnetic cycle. As the video ends, the same large and active sunspot region previously mentioned rotates back into view, this time looking differently.

Bodies in the solar system tend to rotate about an axis parallel to the sun’s axis, and in the same direction. Neptune is a big exception, and there is much theorizing as to why.
Of course, the general phenomenon is taken to be a result of the formation of the solar system from a rotating disk.
I don’t believe other nearby stellar systems are thought to share the rotational orientation of the Solar system. That’s an interesting question though.
that was my thought if similarly formed systems behaved similarly in their rotation
When you look at “stellar nurseries” such as the famous Hubble Eagle Nebula shot, there seems to be quite a bit of turbulence, I guess you could call it, with swirls of various orientations. I don’t think the galactic rotation is imparted to these swirls in the same way the presumed proto-solar system imparted its rotation to the planets. This would be because the galactic scale is so huge, and the stars are imbedded in a thickness much greater than the size of a planetary system.
Just my own musings!
I have the impulse to be a spelling/grammar Nazi, but don’t act on it because I’m sure I’ll screw up my own spelling/grammar whilst correcting others! So I suffer in silence. LOL
well put musings at that
I think you mean Uranus is the exception — its axis of rotation is nearly in the ecliptic, while its system of moons is pretty much normal. Neptune’s basically normal but has a wild group of moons.
Check.
did you say... wild Moon??? 
oh, you said wild BUNCH of moons... nevermind
Silly, ya go at night.
But I thought ya go during an eclipse!
Not if you’re afraid of the dark! ;^P
