Basically, the reason Nirn is at the center of Mundus and all other bodies orbit it is because Mundus is the core of the Aurbis - it is the pearl at the center of the clam, so to speak.
Mundus' layers are
The Heart of the World/Lorkhan (disputed) This is the center, the crux of the whole thing. It's the source of the world's "realness" so to speak.
The Wheels of Lull, a mantle of clockwork, ranging from continent-sized to microscopic, all interlocking and turning in tandem. It's theorized that these are the narrative equivalent of a visual metaphor for the Earthbones, i.e. a way for the mortal mind to understand what the Earthbones do and how they are arranged. Each Earthbone governs some aspect of reality, big and small, and holds the majority of the donated divine power of its patron (so Akatosh, for instance, is the Earthbone of Time, meaning the majority of his divine energy goes into maintaining said physical law).
The Nirncrux, which is an ephemeral, highly toxic and implied to be highly radioactive semi-solid substance that forms a barrier between the surface and the Wheels, to protect both from eachother. May also be a reference to thermal paste, due to the way it disperses the heat generated by the wheels below upwards in a way that mimics geothermal energy irl.
A layer of liquid magma, kept that way by the heat of the wheels below.
The crust, as irl, with tectonic plates and all.
The surface, with all the mortals.
The atmosphere, which all the mortals breathe
The outer reaches of the "reality field" generated by Nirn that keeps things stable and making sense
Outer space, which is not quite Oblivion, but not really Nirn either.
Circling around Nirn, but still within Mundus, are the planets - basically, the divine "corpses" of all the Aedra who donated their power to the Earthbones, as well as Magnus, a hole torn into reality that leads to Aetherius, which is analogous to the sun and provides heat and light and magic to the world.
Nirn is reinforced by the Dragonfire Barrier as well as the Lunar Lattice, which protect it from Daedric incursion, and Mundus as a whole is protected by the Liminal Barrier, which keeps out Oblivion itself, and emanates from the Adamantine Tower, as well as its lesser cousin Towers.
Outside the Liminal Barrier begins Oblivion, where things like linear time or spatial consistency are mere suggestions. Oblivion is very, very far from the Earthbones, meaning they have little to no grip on its substance. This substance, known as Chaotic Creatia (basically raw primal existence) can be shaped by a sufficiently powerful entity, which is how the Daedric Princes maintain their realms and lesser daedra maintain their bodies.
Because Oblivion is characterized by its distance from the limit-imposing Earthbones, there is no clear point where it ends and Aetherius begins, but there is such a point, because the Stars are, like Magnus, holes torn into the fabric of reality that lead there. Some are closer, some are more distant, all determined by when the Magna-Ge that made it fled the world to follow their leader (Magnus).
In essence, in the original plan of Nirn's creation (where none of the magna-ge fled, none of the daedra rebelled and everyone had submitted to Lorkhan's scheme), Oblivion would have functioned as an insurmountible barrier between Aetherius and Mundus.
Aetherius is both the ancestral plane of the gods as well as the baseline of existence. It's what the world naturally tends towards. The reason the gods can exist in four places at once (as gods, as earthbones, as corpses and within Aetherius) is because the very concept of logic itself doesn't grip in Aetherius. It's the state of timeless existence, where all things can be true and untrue at the same time. Meaning that within Aetherius, each Et'ada (original spirit) at once chose to take part in Mundus' creation AND remained behind, a contradiction that can exist because logic like "you can only exist at one point in space at any moment in time" is part of the laws the Earthbones enforce.
Because it gets increasingly philosophical further out, the final "barrier" is more ontological than any real structure. The separation between Aetherius and The Void is a question of being. Things that "are" exist in Aetherius, and everything that "is not" doesn't exist, and is therefore part of the Void.
