I see, thanks. I guess I was thinking of something that 'moved' with the earth, but that probably isn't realistic.

Could something be placed at such a point that then only blocked sun on the far north/south of the planet, near the poles?

Not directly. You could place something in an orbit where it only ever blocked sun at the poles I think, but it would spend the vast majority of its time not blocking sun at all.
