Well I started thinking 3 moons in whole for the Naruto verse?

[Narutp1sasuke2 LetsGo]

Moon no.1 There was already a moon before, Queen Kaguya's appearance on earth.
Moon no.2 The sealing of Kaguya and or the Juubi.
Moon no.3The sealing of Kaguya in one of the dimensions.

If I'm wrong about this explain.
Also noted there was a moon that Kakashi talked about after the sealing of Kaguya "its getting bigger just like the moon". Was the the same moon? Or does Kaguya dimensions represent there own moons?

 

[~Ethereal~]

[Gerkak]

[Chibiusa]

Subtract 1/2 a moon because of Toneri

 

[6thHokage]

Subtract 1/2 a moon because of Toneri

The Last is filler

 

[Seventh Sama]

One moon in the root dimension and two in the nv dimension.
