   No.  "prime" *literally* means "the first" or "number one", from Latin   
   /primus/.

   The "_many_ worlds" _interpretation_ of quantum mechanics is something very   
   different.   
      
   It does not have to do with planets /per se/, but other (parallel)   
   universes: In this interpretation, possible measurement outcomes that were   
   however not observed in our universe/reality are realized, and thus would be   
   observed, in other ("parallel") universes/realities that have the same space   
   as ours.

   There is not only one ("the") sky survey, thus your statement is useless.

   Nobody even said it would be:

   It does move because it has a planet (and three other planets).  But that   
   was not confirmed before the 2024 (and 2025).

   The subject of this discussion are the names and designations of celestial   
   objects.  You are missing the point and are babbling incoherently, moving   
   from one topic to an unrelated next one, like a mentally ill person:   
      
      
      
   Probably someone has told you that before.
