The additional overhead of having a dynamic type would simply be too much. Therefore the StarWrapper is needed when returning Stars as StelObjects, e.g. for searching, and for constellations. The StarWrapper is destroyed when it is not needed anymore, by utilizing reference counting. So there is no chance that more than a few hundreds of StarWrappers are alive simultanousely. Another reason for having the StarWrapper is to encapsulate the differences between the different kinds of Stars (Star1,Star2,Star3).

The ID should be unique for all objects of the same type, but may freely conflict with IDs of other types, so getType() must also be tested.
With this it should be possible to at least identify the same object in a different instance of Stellarium running the same version, but it would even be better if the ID provides some degree of forward-compatibility. For some object types (e.g. planets) this may simply return getEnglishName(), but better candidates may be official designations or at least (stable) internal IDs.
An object may have multiple IDs (different catalog numbers, etc). StelObjectMgr::searchByID() should search through all ID variants, but this method only returns one of them.
