Not sure if someone else mentioned it (and couldnt bother looking through half hundred pages lol, sorry ) - but I think you should call it:
Planetoid
Not only because of the 'planet' this and that all over BUT because the word "planetoid" (Greek for "planet-like"), occasionally is used in English for the "larger asteroids". And we know it's an asteroids, and we know it is huge And I believe you should get rid of the 'club', because NEVERDIE is still using the Club NEVERDIE name on ROCKtropia - and ... ROCK is somehow also taken lol
