Let me just put this in perspective. Tamriel (which I'm sure you've heard of) is one of the largest out of five known continents, which include Tamriel, Akavir, Atmora, Yokuda and Pyandonia. All of these are located on Nirn, the planet in which all known mortal races call home. Mundus is sort of like the solar system, accept instead of pathetic sun being at the center, Nirn is, and all of the other planets and the sun (which in this universe is also called Magnus) orbit it. The closest to Nirn are massar and secunda, the two moons which are visible in the sky at night. Farther away are the planets, each of which is named after one of the 9 divines. Talos is the only one that doesn't have a planet named after him. at the very edge of Mundus orbits the sun Magnus and the stars (also known as Magna Ge), which make up the birth sign constellations from the games. Outside of Mundus Is oblivion, which encompasses it on all sides like an orange peel to an orange. Atherius, home of the divines and afterlife realms including sovernguard, encompasses Oblivion. Beyond atherius is the void, where Padomey, the elder scrolls equivalent of Satin, likes to hang out.

Since Nirn is at the center of Mundus, than it does not have a polar tilt like earth does, so therefore it doesn't have any changing seasons in the games. However the aurora borealis of Nirn is visible from parts of northern skyrim, suggesting that Nirn does have some sort of polar charge and that it does in fact orbit around the sun. It would make sense if this was true, since Tamriel is only in its midevil stage and has not yet developed the scientific tools needed to prove the Nirn - Centric theory.
