Let do a little recap on just Kaguya & Momo.
Kaguya created 6 dimensions—not stars or worlds, but the translation said dimensions— likely via ETSB. These dimensions each contain natural satellites, outerspace and a light source-sun.
Momo said she could also make parallel worlds (to Naruto's own world). Meaning Naruto's entire world either consist of one planet and nothing else or it at least has outerspace, moons, rocks in space and a light source-sun, etc. To think the former is false. To think the latter subsequently means you ought to also accept that Kaguya simply has the capacity to create a parallel world identical to Naruto's world— which means her world has outerspace, with natural satellite, and a light source all exactly like Naruto's own world.
Momo introduced the parallel world talk and created his own which was described identical to Naruto's own world. This means, it also has outerspace, natural satellite, rocks in space, light source, etc. He's apparently described as a God in the novel, game, and manga (not sure about the movie, might have to double check) whom was so dangerous to Kaguya to the extent that she'd enslave an entire planet for chakra (battery) and consume her 2 powerful sons just to be ready for Momo and Kin.
Think about this. If (base) Toneri with Tenseigan can slam the moon on a world to ruin it with utmost ease, and he's unfathomably weaker than Momo, Why does Momo only have moon+?
Though I've observed that some people are vigorously, even at time vehemently, proposing to upgrade the naruto verse to planet+ lvl or so, the implication I get from the source material itself is that they're likely far above the lvl typically proposed.
