Hopefully I'm able to break this down helpfully! :)

Okay, so first we have Mundus, which is the planetary system: Nirn, its moons, and the planets around it (the Divines).

The planets of Mundus are surrounded by Oblivion, outer space, and the other plane(t)s of Oblivion are where the Daedra live, including the Daedric Princes. If it helps, think of the planes controlled by the Daedra as other planetary systems or galaxies. Oblivion's planes share the same stars and sun, though, because the stars and the sun are actually holes in Oblivion leading to Aetherius.

Aetherius is the dimension surrounding Oblivion, and this is where other mysterious beings live and also where Magnus and the Magna Ge fled to, ripping holes in Oblivion which became the sun and the stars respectively. Aetherius can be viewed as the place "outside" the universe of Oblivion. Together, Aetherius, Oblivion, and Mundus make up the Aurbis, which is all of creation.

Finally, beyond Aetherius and the Aurbis is the Void, which is absolute nothingness, and the Void is personified by Sithis.

Did I do a good job summarizing?
