Re: Where Exactly Is The Equator

IIRC:
The south pole is on top of a thick layer of ice that moves slowly.
And plate tectonics will be even more slowly moving the bedrock beneath.

So the south pole won't be static either.

An interesting idea! While I can readily imagine a static S Pole marker (but not N Pole!), we have no prospect of using the centre
as a "fixed point"...
