Do all planets rotate in the same direction in relation to each other?
This Q can be split into two:




Do all the planets in a stellar system always rotate around the star[s] in the same direction as the star[s] itself/themselves?


Question #1 is a duplicate of Why do (most of) the planets rotate counterclockwise, i.e. the same way the Sun does?. As you mentioned, calling it counter-clockwise is simply due to the convention of North on top.




How did the convention of North being the top of maps and globes get established?


Question #2 is about earth science history or the history of cartography. I encourage you to ask that as a separate Q either on the Earth Science Stack Exchange or on the Geographic Information Systems Stack Exchange.

In many cultures, East was/is put on top, as a nod to the rising sun. I imagine if the convention had come from the Southern hemisphere, South or East would have ended up on top.
