Uranus is prograde or retrograde?

Unfortunately for us (who try to explain such things), the definitions have changed over time (at least twice during my lifetime).

It used to be that the "North Pole" of a planet was defined as the one above which the rotation would appear counterclockwise (i.e. to the left). Thus, the North pole of Venus would point "down" when compared to our own.

In that sense, our Galaxy's "Galactic north pole" is pointing "down".

Then someone thought that we could reduce confusion by dividing the celestial sphere in two halves, using the ecliptic.  Any pole that points towards the "north" half of the celestial sphere, would be called a north pole.

Therefore, from its new Galactic north pole, the Galaxy's rotation is retrograde. Under this definition, the uranian rotation is retrograde.

The confusion was not reduced.

Like any other body, it is which way up ypou are Observing

 When its South Pole is facing us it is Prograde and other ways Retrograde

Compered to other Planets it is actually Upside Down

Only its South Pole reacts to Sunlight when it is at Perihelion

Actually it doesn't create confusion among the pros.  Why?  Because you can choose whichever way you'd like it to be.  But then, which is what we've all learned in freshman physics, be consistent with all the other directions in your problem or study.  You see, all you're doing when you pick a direction or rotation to be plus or minus, for example, is defining the coordinate system.  It won't change the physics.

My opinion is that it's retrograde... Maybe the IAU can make the determination that if the pole that rotates counter-clockwise is 'below' it's plane of orbit, the planet has retrograde rotation...
