I read the closest we could likely get to this, in a sci-fi story years back. A habitat on Mercury. It sat on a rail that circumnavigated the planet. The heat of the sun caused the rails to expand, pushing the city forward. This kept it in the most habitable zone, as the planet turned (Mercury has a day longer than its year).
Not quite a zorb, but definitely a clear dome rolling around the planet.

Was that Saturn’s Children by Charles Stross?
That sounds about right. I read far too much sci-fi, and lose track of what is from what book. 😁
