... the extent of her dimensions is known.

Kaguyas parallel time-space's can be confirmed to be atleast the size of a Solar System for these reasons,
 * A sun can be seen in the sky of Kaguyas sand dimension multiple  times.
 * A bright moon can be seen in the sky of Kaguyas ice dimension . Which means that a star must be casting light on the moon.
 * Sun-rays can be seen in one of Kaguyas alternate dimensions.
 * Kaguyas ice dimension can be seen to have a day and night cycle. This indicates the presence of a star.

Pertaining to the Ten Tails "imagine... the very earth and water that compromise this world... flows within every fiber of its being... its life force is that of the planet"
