Huh... Thor is about norse mythology so it is supposed to appear only the nine realms... It's like they have some kind of more importance than the other planets, like they are more advanced, although this couldn't be the case as Earth is surely not one of the most advanced planets in the universe, but they have something who differentiate them. As far as we know, at least Asgard and Earth have knowledge that are other worlds beyond the nine realms, but I don't think they will get into them... It's more to GotG 2
