Perhaps I’m missing something here.  Are we not supposed to say the obvious?  Planets rotate, although some like Venus not very fast.  Therefore, they have an axis of rotation.  One end of the axis is called North; the opposite direction is South.  East is the direction the planet Rotates, and West is the opposite direction. 

Before thinking about Space, perhaps we should think about asteroids, which often have a complex mix if spinning and tumbling.  That takes too much thinking about for me. 

Regarding Compass directions, I was always taught there were 32 points, latterly to give Boy Scouts something to ‘box’ before games apps took over their spare time, but initially because that was the closest course a helmsman could be expected to steer a sailing vessel.  However, as steering got more precise, we see ‘half-points’ and quarter points being used e.g. N1/4E.  This eventually became too much of a mouthful, so even the saltiest seadogs started using 0-360 degrees.

Of course, there are other systems.  DaveP
